Yes, Tuta supports two-factor authentication with U2F and TOTP. Here are details on how to set up your second factor in Tuta.
Go to Settings → Email→ Scroll down to Email addresses → Click "Show" → Click on the plus symbol.
A pop-up opens where you can create the alias email address you want to add. Click on the arrow button to choose the domain for your alias. This can be any of the Tuta domains or of your custom email domains that you have added to your Tuta account. Alias email addresses with your custom domain do not count towards your limit; you create as many as you like.
Please note: It is technically not possible to delete alias email addresses created with a Tuta domain. These can only be deactivated. Deactivated aliases remain linked to your account in case you want to activate them again in the future.
Go here in Settings. You can choose the 'Default delivery': Encrypted ('Confidential') or not encrypted ('Not confidential'). You can also switch whether an email is encrypted or not when composing the email by clicking on the lock symbol. Emails to other Tuta users are always encrypted by default.
Yes. Tuta uses a preshared password for sending an encrypted message to an external recipient, i.e. to someone who does not use Tuta. Please check here to learn how to send encrypted emails to external recipients.
Or watch our quick YouTube tutorial.
Here we explain how to switch the default so that emails to external recipients are sent not encrypted and without a password.
Yes, when sending emails from Tuta to Tuta, all emails are encrypted automatically end-to-end on your device. You do not have to enter any passwords.
Check out our quick YouTube tutorial to see how it works.
Yes, Tuta mail is forever free with 1 GB of free storage for private users. The actual free storage is much higher as we are compressing your emails.
After signing up for Tuta as your new email address, you can easily switch important conversations over from your previous provider. Simply forward all emails from your previous email account to Tuta. Here is an explanation of how you can activate this process in your old email account:

Welcome to the encrypted side!
If you can't log in to your account you might be in one of these situations:
Our secure password reset feature allows only you to reset your password. We have no influence on this process. You can read more about this here.
When you sign up for Tuta, you create an email account. This account initially has one user which is also an administrator. Free accounts only have one user. If you upgrade to a paid subscription, you can add users to your account. You manage the users (deactivate a user, change password) within your Tuta account with your administrator user. You may also allow multiple users to be administrators.
In the diagram the '1' at the arrows means there is one item assigned. A user has one mailbox with one main email address, one (or more) calendar(s) and one address book. The '*' means multiple items may be assigned, e.g. an account has one or more users, a user may have multiple calendars and a mailbox has one main email address and may have multiple email aliases (paid feature) on top.
To learn how to set up a user or create an alias, watch this YouTube tutorial.
Yes, Tuta offers secure business email accounts with lots of whitelabel customizations. You can place the login for your employees directly on your website with a whitelabel domain. Tuta also offers Secure Connect, an open source encrypted contact form so clients can get in touch with you confidentially directly on your website. Learn here how to use Tuta in your organization or company with your custom email domain.
Here's a list of all whitelabel customizations for business use. Here's an instruction how to whitelabel Tuta for your business, how to add the encrypted contact form Secure Connect to your website and more.
Yes, an encrypted calendar is integrated into the Tuta mail client.
Please check that the time zones of your devices are in sync, including daylight saving time.
If you are using Firefox/Tor Browser with resistFingerprinting option in about:config, this automatically resets the browser time zone to UTC, which then leads to sync issues.
Yes, Tuta will include a whole set of collaboration options such as working together on task lists and documents in the future. You can already book this collaboration tool. Right now it is called 'sharing feature' as you can now share your encrypted calendars as well as email templates with other paid accounts. This is the first step, more collaboration options will be added in the future.
Watch this YouTube tutorial on how to share a calendar in Tuta.
Yes, you can customize the logo and colors in Tuta when you book whitelabel.
The date format for your mailbox as well as your calendar is picked either from your language settings in Tuta or from your system/browser settings. If you pick 'English' under 'Settings' -> 'Appearance', the American date format is displayed. If you pick 'Automatic' under languages, the date format of your browser/system is displayed. If you pick any other language, e.g. German, the date format of this language, e.g. German, is displayed.
Yes, right after registration of a business account you will find a data processing agreement directly in Tuta under Settings -> Subscription.
Yes, Tuta as an encrypted email service is perfectly suited for any business that would like to use a GDPR-compliant email service.
Yes, Tuta is a green email service that relies exclusively on renewable energy for all email systems.
The Tuta clients use REST services but there is no public documentation for that API or for a library, yet. Keep in mind that when user data is stored in or read from Tuta, it has to be encrypted/decrypted on the client. You may of course dig into the open source code of Tuta and integrate with your product, but at this time we can not provide any support for this. We will add a public API documentation in the future.
Yes, all Tuta clients are published as open source under GPLv3. Check out our GitHub repository. We welcome you to review the code, to give us feedback or to contribute!
Your friends deserve email security, too!
Invite your friends to Tuta and you both win freebies! If they subscribe to Tuta for one year, you will get credits for 25% of all payments they make within the first month, and they will get one additional free month (13 months instead of 12). Just go to Admin Settings -> Refer a friend and you'll find your personal referral link to share. There is no limit on how many new customers an existing customer can refer.
Please note
Credits received via our referral program will be used for your invoices within Tuta. We will never pay out the referral credits nor do we allow transferring those credits to another customer.
The Tuta referral program is only meant for inviting people you know. We may terminate contracts with people who spam or bulk mail their referral links.
We donate the business version of Tuta to non-profit organizations (NPOs), schools and open source projects. Please find details on how your organization can secure your emails for free or with a discount.
Yes, Tuta supports extensive customization options for business use such as custom colors, custom logo, custom text in the message to external recipients and more. To customize Tuta, you need to book the Whitelabel feature.
After six months without any login activity, free Tuta accounts including all contained data are permanently deleted and cannot be restored.
If you still have the correct credentials for the deleted account, you can re-use the same address(es) with a new paid account by adding them either as extra addresses or users.
Create a paid account (or use any paid Tuta account you already have as the target account). It needs to be a different email address than the deleted one.
Try to log in to the deleted account.
If you enter the correct password, you should see a message below the login form with a "Help" link. Click on "Help".
Enter the address of your new paid account in the "Target account address" field.
If the lost account had a second authentication factor (2FA) enabled, enter the Recovery Code. Please make sure to check our guide on using the recovery code here. Otherwise you can leave this field empty.
Click OK.
Log in to your new account and add the old address(es) under Settings > Email > Email addresses.
If you encounter any issues with receiving emails to your old address, please make sure to wait up to an hour and try again. Otherwise, please read our guide "I have reactivated my deleted address but do not receive Emails."
Make sure that you have waited one hour before trying to receive emails to the reactivated address.
Make sure that you have added the address either as an extra email address or a user to your new account under Settings → Email → Email addresses or Settings → User management. If you are not sure, you can watch our short Youtube video on the difference of email aliases and users.
Unfortunately, some services put email addresses on a blacklist after receiving a bounced delivery report and do not send emails to them at all anymore. If you are trying to receive a password reset link or a login confirmation from an online service, your address might have been banned during the time when your account was inactive. In this case, we cannot do anything from our side. Please contact the service in question and have them check the status of your email address. This usually solves the issue.
The recovery code is a 64-character long string and consists of the characters a-f and 0-9 only. This means that there could be no confusion between similar looking letters and numbers like the letter "o" and the number zero "0" for example.
This string is separated into 16 ordered groups each consisting of 4 characters.
When entering the recovery code you have to include the spaces between every four characters and all letters must be entered in lower case.
You can share a contact list with any Tuta user. Go to contacts and click the three dots next to your contact list's name. When sharing you can also specify one of three different access permissions to the list:
The recipient will receive a notification email and will be able to see and accept the invitation under the contact lists section in the contacts view.
Recipients of shared contact lists can change the display name of the list on their account.
Contact lists are lists of addresses which can be used in Tuta to easily and quickly include multiple recipients when sending emails, event invitations or even when sharing contacts.
The list can include existing contacts or other addresses and can be shared with other Tuta users.
Here you can read how to create and use contact lists or how to share contact lists.
Contact lists are available on all new paid plans. To create a contact list navigate to contacts and click on the plus button. On mobile devices, open the left side menu in order to see the contact lists section and the plus button.
An editor pop-up window will open where you can enter the name of the new contact list and optionally add entries below.
When you start typing an address you, will see suggestions from your existing contacts but you can also add addresses which are not yet in your address book.
You can add multiple addresses and click "Save" when done. If you later decide to rename or delete the list, simply click on the three dots button next to its name.
Once you have a list created, you can use it in any recipient field in Tuta. For example when sending an email or an event invitation. Just enter the name of the contact list in the address field.
Here you can read how to share contact lists.
You can switch the subscription in Tuta by upgrading or downgrading.
We plan to add Bitcoin as a payment method to Tuta in the future. You can already buy Tuta gift cards with the cryptocurrencies Monero or Bitcoin or with cash via our partner Proxystore.
To redeem a gift card from Proxystore, please follow the instructions in Proxystore right after ordering the gift card. You will get a gift card link. When you use the link, you need to choose 'Use existing account' or create a new account, depending where you want to apply the credit to. Once you have added the gift card, you can check the credit on your account under Settings -> Payment. When upgrading your account, you can now choose 'Account balance' so that no payment details need to be linked to your Tuta account.
When you buy a gift card (by clicking on the present symbol to the left), a popup will appear with some buttons that will give you the option to a) send an email containing the gift card link, b) copy the link to the clipboard, or c) print off a graphic containing a QR code. The popup can also be viewed later under Settings -> Subscription -> Gift cards.
The person who wants to redeem the Tuta gift card can then either click the link or scan the QR code, and they will be taken to a page where they can redeem it by following the steps provided (select 'Use existing account' or create Tuta account, then redeem).
To redeem the gift card on your own account, simply use the link to login with your account. Then the credit of the gift card will be applied to your account automatically. You can check your credit under Settings -> Payment.
The terms and conditions can be found here.
When booking a paid subscription in Tuta, you can pay via Credit Card (Visa, Mastercard, American Express), via PayPal or via bank transfer. Payment via bank transfer is only available for business customers in the EU. If you would like to pay your personal plan via bank transfer, please contact our sales team.
If you have problems paying for your Tuta subscription, please contact our sales team.
Yes, you can buy gift cards and add them to your own account. Once the credit is added to your account, it does not expire. It will be used for future invoices. This gives you the option to top up your account whenever it is convenient for you. You can check your credit under 'Settings' -> 'Payment'.
You can secure the stored app login with a pin, pattern or biometrics (fingerprint, Face ID etc.). Please go to Settings -> Login -> Unlock method to activate this.
This option will only show after you have stored your login credentials in the Tuta app. Upon login tick the checkbox 'Store password' to store your login credentials.
Tuta uses a password strength indicator that takes several aspects of a password into consideration to make sure your chosen password is a perfect match for your secure email account. You can find additional tips on how to choose a strong password here.
Tuta has no limitations in regard to the password length or used characters; all unicode characters are respected.
If you click on 'Logout', you log out. Please note: If you have previously saved the password, you are now logged out, but the password is still saved for automatic login. To 'unsave' the password, please log out. The login screen appears, click on 'More' and 'Delete credentials'.
A secure password is one that is random enough that it cannot be guessed in a feasible amount of time. But random strings of alphanumeric characters are hard to remember. That's why we have implemented a passphrase generator that finds a good balance between security and memorability. The generator chooses six easy words from a huge curated list and outputs a passphrase that is secure as well as easy to type and remember. Here are more tips on how to create and remember a strong password.
Your password is salted and hashed with Bcrypt on your device before being transmitted to Tuta. Bcrypt is the most reliable method because brute-force attacks need much more time in comparison to conventional methods such as MD5 or SHA. With this method we guarantee an integrated confidentiality and we allow you to access and decrypt your emails from desktops and mobile devices instantly.
No. When a password is used for authentication (login), it is not necessary that it is known to the server you want to authenticate with. The server only needs a fingerprint (hash) of your password. With Tuta your hash for authentication is calculated by your browser and only the hash is being sent. Your password never travels the Internet in plain text and it is never seen by our server. As hashes are non-invertible, the server is unable to reconstruct your password from the hash. The server is not able to decrypt your message, but still able to log you in.

If you think your password was disclosed to someone else but you can still log into your account, please do the following:
If the attacker had been logged in as well, changing the password automatically logs them out.
We encourage you to always use 2FA with your accounts as it makes it close to impossible for an attacker to log into your account.
If you can not log into your account any more, please check this FAQ.
For the email encryption between users, Tuta uses a standardized, hybrid method consisting of a symmetrical and an asymmetrical algorithm. Tuta uses AES with a length of 128 bit and RSA with 2048 bit. Emails to external recipients are encrypted symmetrically with AES 128 bit.
By default, we do not log IP addresses when you log in or when you send an email. The IP addresses of sent and received emails are stripped so that your location remains unknown.
We only log IP addresses of individual accounts in case of serious criminal acts such as murder, child pornography, robbery, bomb threats and blackmail after being served a valid court order by a German judge. You can find details on this as well as on German data protection rights on our blog.
Learn on our blog how Tuta fights illegal mass surveillance by providing an anonymous email service. Upon registration you do not need to provide any personal data (e.g. no phone number required). We will also make it possible to pay for Tuta with Bitcoin.
Tuta automatically encrypts all emails stored in your mailbox. Emails between Tuta users are automatically encrypted end-to-end, emails to external users can be secured with the help of a password. Here we explain the differences between a confidential (end-to-end encrypted) and a non-confidential email.
Independent of the end-to-end encryption, the transport between client and Tuta servers is secured with TLS to maximize security.
Watch our YouTube email encryption guide for Tuta - the quickest email encryption guide you can get!
A deleted email address (also if it is an alias) will not be recycled for security reasons. There must be no possibility that someone else is able to register your previously used email address, and then, by accident, receive a confidential email that was meant for you.
Free of charge accounts are deleted after an inactive period of six months. A regular login is necessary to prevent automatic deletion. We delete such accounts for security reasons and also to allow us offering free of charge Tuta accounts at all. However, the email addresses of such deleted accounts may be taken over into another paid account and re-used as email aliases or additional user addresses if you still have the valid login credentials.
To re-use the email address of the inactive account
Then you can add the lost address(es) as an alias (or user) to the target email account. We call it merging of addresses.
Your private and your public keys are generated locally within your browser upon registration. Your private key is encrypted with your password. This way your login password receives the status of the private key. The key is encrypted so strong that only you can use the key for encrypting and decrypting data. This is why a strong password is essential. An automatic password check on the client makes sure that you use a strong password. Your password is never transmitted to the server in plain text. It is salted and then hashed with bcrypt locally on your device so that neither the server nor we have access to your password. With this innovative design you can access your encrypted inbox from any device (desktop, mobile) easily.
Tuta does not load pictures automatically when you open an email. When you load external images manually, please note that
Here we explain how to display external images. Please read here how we make sure that you can use Tuta as an anonymous email service.
We require all messages to be authenticated. Without authentication, the email could be coming from anyone or could be modified so you should always treat such emails with scrutiny. If you see a message where the authentication has failed (red warning banner), you should be especially careful as it means that this email was likely faked.
Phishing is a name or type of online scam in which criminals try to look like a legitimate sender in order to get your data such as credentials or credit card data. Phishers use very sophisticated psychological techniques and develop very realistic copies of real websites and emails.
If you see a phishing banner, it means that some parts of this email match our phishing signatures after other users reported similar emails as phishing. Please be extremely careful with such messages. Usually phishing emails contain a special link to the website which looks real but it actually is not. If you think that the email is legitimate and you opened the link, please make sure to check the full website URL: Check that you see all of it, sometimes only one part or one character may be swapped. Here is more information on how to prevent email phishing attacks.
You can mark an email as not phishing so you will not see the warning message any more for this email.
We never send you emails with links where you need to type in your password. We encourage you to always protect your login credentials with 2FA as this makes it close to impossible for an attacker to log into your account.
If you already fell for a phishing attack, please check this FAQ.
The Tuta servers are located in secure and ISO27001 certified data centers in Germany. All saved data are subject to the strict German privacy protection laws. Independent of that all data is end-to-end encrypted and cannot be read by the Tutao GmbH as the provider or by any third party.
Yes. You can view and remotely close active sessions under Settings -> Login.
Check our How-to to learn how to enable storing of closed sessions to monitor whether someone else has access to your account. To guarantee the users' privacy, we have implemented the feature as follows:
Tuta encrypts all data stored in your mailbox (contacts, emails, email signature, inbox rules, invoice data, payment method, certificate and private keys of your own domains). When sending an email, Tuta encrypts subject, content and attachments automatically.
You can find a detailed explanation about what is encrypted in Tuta on our security page.
We can read only the following metadata:
We are looking into possibilities to hide the metadata in the future as well.
Yes, you can always access the emails sent via Tuta through the link from your latest notification email. Old notification links from the same sender are de-activated for security reasons. Your exchanged password, however, stays unchanged as long as the sender does not change it. If you have saved the password upon accessing your confidential emails in your browser, you do not have to re-enter it.
Email aliases are additional email addresses that you can use with the same mailbox without having to switch accounts. Additional email addresses are included in all paid plans of Tuta. If you upgrade to any of our paid plans, you can add alias email addresses.
Find out more about Tuta aliases in our How-to (create alias, change default sender, etc.). Learn here what the purpose of an email alias address compared to a user is and how aliases can increase your security.
Yes, email addresses are automatically added to your encrypted Tuta address book when sending an email unless you deactivate this feature. You'll find details here.
Yes, any paid subscription of Tuta comes with custom email domain support and unlimited email addresses for custom domains. Multiple domain support is also available in Tuta. Please check our pricing page for details.
Please refer to our how-to to learn how to add your own email domains to your Tuta account and how to make sure that your records (MX, SPF, TXT, DKIM, DMARC, CNAME) are set up correctly in your DNS as well as how to activate/deactive catch-all and more.
In addition you can watch this YouTube tutorial to learn how to set up your own domain in Tuta.
Yes. Before logging in, click on 'More' and 'Switch color theme' to switch to the dark theme. This works in all Tuta clients (web, desktop, apps). Alternatively, you can go to 'Settings' -> 'Appearance' to switch to the dark theme. To add a custom theme, you need to book whitelabel.
You can download the Tuta desktop clients (Windows, Linux, Mac OS) on our homepage.
Yes, Tuta uses different variables to calculate email limits for individual accounts. This is necessary to protect our free and anonymous email service from spammers who try to abuse Tuta. If spammers were able to abuse Tuta, it would harm all Tuta users - ie Tuta domains could end up on email spam lists, which we have to prevent under all circumstances.
If you receive the following message in your Tuta account "It looks like you exceeded the number of allowed emails. Please try again later.", the anti-spam protection method has stopped your account temporarily from sending new emails. Please wait a day or two to send new emails again.
If you need to send more emails immediately, please upgrade to any of our paid plans as limits for paying users are much higher. Simply click on 'Plan' in your side menu bar of Tuta.
Please note that Tuta is not meant for sending out mass mailings such as newsletters. Please read our Terms & Conditions for details.
Yes, with a paid subscription you can set up email notifications to any email address under 'Settings' - 'Email' - 'Notifications'. You will be informed about new emails once until you log in. Only if you have logged in to view this email, Tuta will send another notification to keep notification emails to a minimum.
As a Free user, you can receive push notifications in the browser, the Android & iOS app as well as the desktop clients.
You can request and discuss new features with us and other users in our Reddit community. You can check whether someone has already requested this feature and whether we have already added it to our Roadmap.
Emails: You can export/download individual emails or batch-export emails by using multi-select. Email import is not yet possible. We plan to support email import as well as an even easier export function with our new secure desktop clients.
Contacts: You can import and export contacts via vCard.
Calendars: You can import and export calendars via .ics. Login with a browser and click on the three-dot button next to the calendar you wish to import data to or you wish to export.
Yes, Tuta supports an unlimited number of inbox rules / filters for paid accounts. Check our how-to to see how to set up inbox rules.
The language in Tuta is taken automatically from your browser or system settings. Please change the language there. Alternatively, you can go to 'Settings' -> 'Appearance' to switch the displayed language for Tuta.
We also invite you to join our translation project to improve Tuta in your native language!
Yes, you can add existing email addresses (e.g. Alice2, Alice3) as aliases or users to a paid account (Alice1):
Please note: You are only transferring the email addresses. Emails and contacts stored in the deleted accounts (Alice2, Alice3) are being deleted. Please export important emails before deleting the accounts.
In the mobile app, you can currently only login with one user. To switch to another user, you must log out and log in again. You can login with multiple users in the browser by opening several tabs or windows. In the desktop clients, you can also open several windows to login with multiple users.
Please check the app settings on your phone. As we do not use Google's push notifications service, battery optimization must be disabled for Tuta to receive push notifications instantly.
This is necessary to offer you an open source email service free from any links to Google.
Yes, the Tuta mobile apps for iOS and Android as well as the Tuta desktop clients can store a local copy of your mailbox.
To activate local storage of data, please store your password within the client. By default, all contacts, calendars, and all emails sent and received within the last 30 days are then stored locally.
With all of Tuta's paid subscriptions you can increase the timeframe for which emails should be stored under Settings -> Email -> Local data. Please note that the emails must be loaded once for creating the local copy.
Current encryption standards like PGP and S/MIME have several issues that we plan to address with Tuta. These standards do not support forward secrecy and are not resistant to attacks from quantum computers.
In addition, it is important to us that the subject line in emails is also encrypted. That's why we have developed a solution that is also based on recognized algorithms (RSA and AES) and that automatically encrypts the subject, the content and the attachments. In the future, we plan to upgrade these algorithms to quantum-resistant ones that also support forward secrecy. You can find more information on why Tuta does not use PGP here.
We also see the importance that Tuta needs to be interoperable with other encryption solutions. We will develop an API so that Tuta users can communicate with users of other secure services confidentially in the future.
No, Tuta does not support plus addressing (xyz+username@tutanota.com) for Tuta domains. If you want to register with different plus addresses at different sites, you can upgrade to a plan that supports alias email addresses (limited to the number of aliases you book). Alternatively, you can use a custom email domain with catch-all to create an unlimited number of plus addresses for incoming emails.
Yes, Tuta comes with full-text search of your encrypted mailbox. In the free version, search is limited to four weeks into the past due to heavy server load caused by the encrypted search feature. Learn here how you can improve your search results. The spam folder is excluded from search.
Search is executed locally via an encrypted search index to guarantee security and privacy of your data as well as your search queries. As the search index needs to be stored in your browser, it does not work in private mode/incognito mode. Read here how our innovative full-text search on encrypted data works.
Tuta desktop app uses system keychain to be able to encrypt sensitive details such as credentials and alarms. On Linux there must be an app installed which provides secret storage (org.freedesktop.secrets interface). This is usually set up together with the rest of the desktop environment but sometimes it requires manual setup. Installing GNOME Seahorse and configuring keychain there should be sufficient. KeePassXC is another provider which can be used but it must be additionally configured.
The Settings are in the navigation menu to the left.
Yes, you can change the signature in Settings -> Email. Every account can change their signature. To support our free and secure email service, please leave the link to our homepage in your signature.
Yes, Tuta uses a spam filter to keep your mailbox free from spam. We are improving this filter continuously. Should you receive spam emails in your inbox, you can also configure your own spam rules here to deny or allow certain email addresses or domains. If a sender is blocked (rejected) by the spam filter, you can allow the sender for your account.
In paid accounts, only admins can create spam rules that are being applied across all users.
Yes, Tuta supports HTML editing options (embed images, add lists, bold, italics, underline, monospace, add hyperlinks, align the text left, center, right, justified, change text size, remove all formatting). These are explained in our how-to along with lots of information on email handling.
Yes, all emails in Trash or Spam are automatically deleted 30 days after the emails were moved to these folders. You can also manually empty these folders with one click. Please note: Emails deleted from Trash or Spam folders are physically deleted and can't be restored.
You can download the Tuta app from the following stores:
In addition to that, you can also directly download and install the APK for Android. Keep in mind that you will not get updates automatically if you install the app manually instead of using an app store. You can add our blog to your RSS-reader with this link to get notified about updates: RSS-Feed
Web: The web version of Tuta is automatically updated whenever you reload the page. If an update is released while you're using Tuta, you will see a pop-up notification prompting you to update. All you have to do is click on "Refresh" to update. If Tuta does not update in your browser, you can trigger a manual update by loading Tuta in private/incognito mode of your browser.
Desktop: The desktop app automatically checks for updates by default. Whenever it finds an update, it is downloaded in the background and you receive a push notification. Under Settings -> Desktop you can activate/deactivate automatic updates or manually check for updates
iOS/iPadOS: Please use the App Store to check for Tuta updates.
Android: If you're using the Google Play store, please check there for updates.
F-Droid: Please make sure that you open F-Droid and navigate to the updates page. Swipe down anywhere on the screen to sync your repositories. Once done, you will be able to see any available updates for Tuta.
Please note: Our system sends update notifications via email whenever we detect an active session from an outdated client. Please go to Settings -> Login and close any unused sessions under Active Sessions.
Download: You can download the Tuta clients here.
If you add another user to your account (family member, partner, team member etc.), you get the following benefits:
Here are more details on user management. If you do not need these sharing options, you can also upgrade accounts individually. Please check our pricing calculator for details.
Furthermore, we have recently added a sharing feature for the encrypted calendar which we will extend in the future. Sharing of entire calendars only works with other paid Tuta accounts.
WebView is a system app on Android devices which allows us to display web content inside the Tuta app. Newer versions let us use newer technologies to make the app smaller, faster, more beautiful and more reliable. If you experiencing issues or bugs with the Android app, updating WebView has a good chance to help.
Some accounts are automatically marked for approval upon sign-up to prevent abuse. This often affects IPs from VPN services or Tor as spammers try to bypass our anti-spam protection method by abusing these services. Please read here why the 48-hour wait is necessary to protect your privacy to the maximum with a truly anonymous email service.
During these 48 hours emails cannot be sent or received. Please do not share your new email address before the blocking has been lifted automatically.
Tuta uses its own Captcha so that we do not have to depend on using Google Captcha. This enables us to offer an open source email service without any links to Google.
The Tuta Captcha shows a clock. You need to enter the displayed time with four numerals, including the colon in the middle. If the displayed time is 8.30 for example, you have to enter 08:30 or 20:30 exactly.
Please check whether the sender was blocked by following this instruction.
Sometimes newly created email addresses are put on hold for 48 hours to prevent abuse. It is important that you do not share your email address until this block is lifted automatically. If you do use the email address to register elsewhere or sign up for newsletters before the block is lifted, this service will send you a confirmation email, which will bounce with a temporary error. This might lead to problems registering with this service, even in the future.
The same issue sometimes affects users whose Tuta email address has been blocked, for instance due to inactivity. Even after you reactivate your Tuta email address, this might lead to problems receiving emails from online services because they stopped sending to your address due to bounces. In that case, please contact the service in question and ask them to start sending to your address again.
Most websites and online services let you register with your chosen Tuta email address just fine. Unfortunately, we have received reports by users that some websites block Tuta email addresses for registrations. Please check these options to resolve this situation.
If you would like to inform us about abusive usage of one of our domains (tutanota.com, tutanota.de, tutamail.com, tuta.io, keemail.me, tuta.com), please contact us at abuse@tutao.de. Please forward the abusive message to us if appropriate.
If you are a Tuta user and have received a phishing email, you can report this email by clicking on the three-dot button to the right and then click on 'Report phishing'. Here are more details.

We at Tuta take utmost care to secure your mailbox to the maximum. The Tuta code is published on GitHub, and we invite security experts to check the code. In case you find a vulnerability in Tuta, please report it directly to us so we can fix it.
Yes, you can downgrade back to free anytime. Before this, you need to disable all extra bookings. You can keep your main Tuta email address as a free account.
Check here to see how you can upgrade or downgrade.
Yes, the Tuta Transparency Report is updated every six months. You can check it here. It also includes a Warrant Canary.
You may opt in to share your Tuta usage data with us to help us test new features and find issues with existing functionality. This consent is optional and may be revoked at any time in settings.
We use usage tests only to improve Tuta. To evaluate usage tests, we will generate and store a random identifier on your device that is shared across all logged-in accounts. Since your usage data is about your interactions with the app, we do not collect any personally identifiable information.
Your anonymized usage data may be used for research purposes, but apart from this we do not share your usage data with third parties.
Usage data usually takes the form of one of the following:
We recommend setting up 2FA because of its security benefits. Learn in our online security guide how 2FA helps you to keep your emails safe from hackers.
Registering your second factor
You can connect your second factor with Tuta in Settings -> Login. As admin you can setup second factors for your users in Settings -> User management.
Tuta currently supports the following second factor types:
Second factors can be added by administrators and users, but only admins can remove assigned second factors.
Note: If you lose your second factor, you will no longer be able to login to your account. To prevent this, you can add multiple second factors. Additionally, please note down the recovery code shown to you when adding a second factor.
Authenticating with your second factor
During login you have to authenticate with one of your second factors. Alternatively, you may also accept that session from another logged in client. If your browser does not support the second factor you had registered, you can only accept the session from another client.
How to reset your second factor if you lose it
For resetting your second factor, you will need your personal recovery code and your password. You can view and also update your recovery code in Settings -> Login.
If you have lost your second factor, click on More -> Lost account access on the login page. There you will have to enter your recovery code as well as your password to delete all your second factors.
Email encryption is needed whenever you want to send a confidential email. That is whenever your email contains personal information that should not become public. The following examples show the differences between end-to-end encrypted, confidential emails and emails that are not being end-to-end encrypted in Tuta.
In this YouTube tutorial we demonstrate how you can send an encrypted email in seconds.
Alice is registered with Tuta, Bob may be registered with Tuta or an external recipient and Carol is not registered with Tuta. In any case all emails (including attachments) are stored encrypted on the Tuta servers. Independent of the end-to-end encryption, the transport between client and Tuta servers is secured with TLS to maximize security.
Sending and receiving end-to-end encrypted emails
The email is encrypted on Alice's client, stored encrypted on the server and can only be decrypted by Alice or Bob.
Sending non-confidential emails
The email is sent via SMTP to the recipient. Still, the sent email is encrypted for Alice on the server and then stored.
Receiving non-confidential emails
When the SMTP email is received by the Tuta server, it is encrypted for Alice and then stored on the server.
If you own one or more domain names that you want to use with Tuta, you can add these domains to your paid subscription of Tuta. The setup wizard for your custom email domain will guide you through the process in just four small steps. In each step the wizard will explain, which configuration changes you have to make. If you don't have a Tuta account, you can register here.
The setup wizard for your custom email domain can be found in 'Settings' -> 'Global settings' -> 'Custom email domains' by clicking the '+' button.
Check out this YouTube tutorial to learn how to set up your own domain in Tuta.
In order to send and receive emails with your custom domain in Tuta, you need to configure the following types of DNS records in the settings of your domain name provider. Prior to configuring those DNS records the wizard will allow you to create new users or email aliases for your custom domain in order to have a smart switch to receiving emails in Tuta.
The exact values that these DNS records should point to will be shown to you in the setup wizard.
The MX record is necessary to relay emails for your domain to the Tuta servers. The SPF TXT record marks the Tuta server as valid sender of emails from your domain. The _domainkey and _dmarc records make sure your emails are signed with DKIM and sender spoofing of your domain's email addresses can be detected automatically by the recipient mail servers. The MTA-STS records make sure that transport encryption and authentication is used between different mail servers.
Tuta will indicate if the DNS records are fine for all your domains or if there is something that has to be changed.
Please note that with some domain name providers it may take up to a few hours before changes to your DNS records become visible for other mail servers. You can check your DNS settings here.
Please note that we do not support email import, yet. We plan to enable import in the coming months. For now, we recommend to keep your old mailboxes as a reference when moving to Tuta from another provider or storing all emails locally.
On our business site, there is a summary of all available features of Tuta's secure business emails.
When you create a new Tuta account, our secure password reset feature empowers only you to reset your account yourself. Please make sure that:
In case you can't login to Tuta, please make sure that:
We do not know your password and can't modify your second factors. However, there are different ways on how to regain access to your mailbox in case of a lost password or a second factor.
Administrator is available
If you are a member of an organization or a business: Ask your administrator to reset your password. Each administrator can reset the passwords of other users and admins. If you want to make sure to never lose your paid account, it's best to have at least two administrators.
Recovery code is available
Your recovery code is your personal code to resetting your account. If you did write it down when you created your account, you can reset your password or second factor using your personal recovery code by clicking on More > Lost account access on the login page.
You can view and also update your recovery code in Settings > Login. You can also find more information on this secure reset feature on our blog.
With 2FA enabled, you will need 2 out of 3 to reset your Tuta account:
Click here to reset your password. You will need your second factor (if 2FA enabled) and your recovery code.
Click here to reset your second factor. You will need your login password and the recovery code.
Please note: If you lose your password and your second factor, there is no option to reset your Tuta account with the recovery code.
To search your encrypted mailbox, simply click on the top search field or press F.
It is very important to know that you can search for multiple words at once, for instance sender's email address, keyword and file ending. Such a search could look like this: alice@tutanota.de meeting notes pdf
When you press enter, Tuta takes you to a more detailed search mask. The free search feature goes back one month into the past.
The detailed search mask lets you specify the time frame which should be searched (one month for free users). The unlimited search feature also lets you filter your search, e.g. who sent the email, to whom did you send the email, was the search query contained in the subject or in the body, what folder should be searched.
As all data in Tuta is encrypted, using our innovative search feature causes a lot of traffic. This is why unlimited search is only available to paying users. Learn here how you can benefit from extra features by upgrading.
Please note: You can only search emails and contacts, thus, the search field is not shown when you are browsing the 'Settings' of your mailbox.
To update WebView it is enough to install or update one of the following apps:
For most Android versions: Android System WebView
For Android N (7), Android O (8), Android P (9): Chrome
For some specific Android installations (e.g. custom Android ROMs, some LeEco devices) the procedure might be different or might not work. Please refer to your device or OS vendor for instructions.
Advanced: Changing WebView provider
If you do not want to use Google-provided WebView, it is possible to install some other app (like Chromium or another WebView build) which can be used instead. Please refer to these instructions. Please note that we can only support Chrome/Chromium based WebView.
When sending an encrypted email to an external recipient, you need to specify a password when composing the email.
Once set, the password will be automatically saved along with the contact in your Tuta address book, which makes your encrypted address book the password manager for your external contacts. Next time you write an email to that recipient, you simply specify the email address and Tuta automatically enters the password. The password needs to be exchanged via a second channel. If you would like to change the password, you can either do this within the contacts view or when composing a new email to this external recipient.
The external recipient
Note: The link within the notification email contains a salt which is needed for decryption along with the password. Thus, someone who wants to intercept your encrypted messages needs the exact link and the password. (An old link gets deactivated as soon as you send a new email to the same email address.)
Watch our YouTube tutorial on how to send an encrypted email to external recipients.
When you select an email, these options show up to its top.
The top email menu has the following options:
If you want to print an email as pdf, you can use the browser function for printing.
Sending of emails
Condensed email window.
Enlarged email window.
When writing an email you can use these text editing tools
Please use mouse-over in the web client to see what symbol represents what function. The Tuta text editing tools enable you to embed images, add lists (bullets and numbers), change texts to bold, italics, underline, monospace, add hyperlinks, align the text left, center, right and justified, change the text size, and remove all formatting from selected text.
Depending on the width of your browser Tuta displays the left Settings menu, your folder list, your mail list, and the selected mail.
Spam detection in Tuta is multi staged. For incoming unencrypted SMTP emails, the received email is checked against DNS spam lists first. In a second stage we filter emails by executing content checks and mark emails as spam or not. Emails that have been marked as spam will be moved to the spam folder of your mailbox. In a third stage we filter spam on the base of user defined email sender lists. This list provides the possibility to classify email addresses as spam or not as spam. The check is active for all incoming emails and can be configured by the administrator. The rules are valid for all users.
As administrator for a Tuta account you can configure the email address list here in Settings.
Within a received email, please click on 'Show more', then click on the From address to assign the email address, the domain, or the top level domain with one of the following spam rules:
The "No spam" rule has a higher priority than "Always spam" and "Discard" has the lowest priority.
You can set spam rules for sender addresses (highest priority), domains (lower priority), and top level domains (lowest priority). To add a spam rule for a domain, just enter the domain like xyz.com without putting an @ in front. This rule will also apply to emails sent from a subdomain. To add a spam rule for a top level domain, just put in com - for example - no dot is needed before this.
Rules for domains are restricted. You are not able to assign the rules "Always spam" and "Discard" to Tuta domains, neither to your custom domains.
You also have the option to allow all emails. To do this, create a spam rule and put in an asterisk * where you would usually put in the email address that the rule should apply to.
To insert a template into the mail editor, please login to Tuta in the browser or in one of the Tuta desktop clients:
If you have created several language versions for this template, you can choose the correct one after hitting tab (step 2).
Alternatively, you can access your templates by typing ctrl+space, or from the editor toolbar. There you can search for the correct template and insert it.
Tuta blocks automatic image loading to protect your privacy. To load external images, please click on 'Show' above the mail body to load the image for now or on 'Always trust sender' to always load all images sent from this email address. Please note that you have to allow images from a trusted sender on all your devices once. In the case that mail authentication fails or is non-existent, images will not be loaded even if the sender has been allow-listed. Inline images are displayed directly as no external content needs to be loaded.
How to receive blocked emails.
Go to 'Settings' -> 'Global Settings' -> 'Rejected email senders' to check whether any email to your account has been blocked due to the sender being listed on a spam list. You can click 'Refresh' to refresh the list in case you are waiting for a registration email. If a blocked email is shown here, you can allow the sender so that emails from this sender will reach your inbox in the future.
'Login' shows you several info items about your Tuta account.
Here you can configure how you want to send your mails.
'Inbox rules' (filter): Click on 'Show Inbox Rules' and then on the plus-button. A pop-up with three options opens: 'Field', 'Value' and 'Target folder'.
For inbox rules we support javascript regular expressions. You have to enclose the expression with slashes / like the literal definition of regular expressions. More information can be found here.
'Notifications': Click on 'Show' and the plus symbol. A pop-up opens where you can enter an email address that should be notified once a new mail arrives in your Tuta mailbox.
Push notifications
Please login to Tuta in the browser or in one of the Tuta desktop clients. In Settings -> My Templates you can create templates to answer repetitive requests faster. Click on 'New template' to create new template.
For your template, enter a Title, a Shortcut, select the language (here: English), the content. When using templates, you will need the shortcut to find the correct template. The content will be added to the mail editor automatically.
Here we explain how to add templates to an email or you can watch our YouTube tutorial on email templates.
Go to Settings -> Payment to view and update your payment details.
Once upgraded you can add 'Extensions':
To upgrade a Free account (or downgrade), please go to Settings -> Plan -> Plan and click on the pen symbol. Then you can pick another plan (picture below).
Under Settings -> Plan you can also sign the 'Order processing agreement' if you need to comply with the GDPR, switch your 'Payment interval' from monthly to yearly, check your price per year, and add more 'Extensions' or order gift cards.
When you order the Whitelabel feature, you have two options: The Whitelabel feature is already included in the Pro subscription. Alternatively, you can order it separately in your paid account. Your whitelabel domain can be any subdomain, and might look like 'secure.mycompany.com' or 'email.mycompany.com'. In order to setup whitelabel you must be able to set the CNAME DNS entry.
Now you can open your website in your browser and see the Tuta login with your customizations.

The application may also be uninstalled silently, by passing /S to the uninstaller (in the installation directory under Program Files).
Sometimes the browser does not recognize the newly installed Tuta desktop client as the default mailto app. If clicking a mailto-link does not open an email in the desktop client, please make sure that the Tuta desktop client is activated as the default email app in your system settings as described above.
If everything is set up correctly, these instructions might help to troubleshoot:
Firefox
Chrome
The Windows desktop client comes with MAPI support. Via the context menu of a file -> Send to... -> Email recipient - you can directly attach files to a new email.
In various programs (Office, Adobe Acrobat Reader, SAGE50) you can use the "Send document as mail" function and attach the currently opened file to a new email. You can find more details on our blog.
You need to activate the 'Run in background' option to receive notifications from the desktop client. This option appears in your notification area on Windows and in the Tray on Linux.
When it is active, the desktop client will not terminate when all windows are closed and instead remain in the background to provide desktop notifications in case of incoming email or calendar alarms.
If you can't see the tray icon on Linux despite the app running and the 'Run in background' option being set to 'Yes', please refer to your distribution's documentation to enable tray icons or AppIndicators. On MacOS, this option is not visible, and the dock icon is always used to provide a context menu.
If you still do not receive notifications, please check that you do not have focus mode, alarms only, or do not disturb modes on. You can also check the desktop settings of the client.

You can sign up for a Tuta account in four easy steps.
You choose one of the available free or paid subscriptions.
You choose your new Tuta email address, set a password, and confirm that you have read our terms and privacy policy and that you are above 16 years old.
Then your account is being prepared. If applicable, you can add your custom domain later.
You choose a payment method, enter your payment details and confirm. If you registered a free account, this step is not required.
The last step is to make sure that you never lose access to your Tuta account: Tuta asks you to write down or print your recovery code. Please take the time to store your recovery code in a safe place. The recovery code is the only way to reset your password should you lose it in the future.
To get started, you need to pick one of the available Tuta domains for your account.
With any of the paid subscriptions, you can later add alias addresses and your custom domain to your new Tuta account.
Tuta uses its own Captcha so that we do not have to depend on using Google Captcha. This enables us to offer an open source email service without any links to Google.
The Tuta Captcha shows a clock. If applicable, you need to enter the displayed time with four numerals, including the colon in the middle. If the displayed time is 8.30 for example, you have to enter 08:30 or 20:30 exactly.
Tuta protects your private data by building the most secure email service. We do not track or sell your data and do not post ads. If you share our mission of making the web more private and secure, please upgrade your Free Tuta account. You will not only support an amazing service, but you will also get lots of extra features.
In you mailbox, go to 'Settings' -> 'Email' -> 'Inbox rules'
Under 'Inbox rules' (filters) click on 'Show Inbox Rules' and then on the plus-button. A pop-up with three options opens: 'Field', 'Value' and 'Target folder'.

An email alias is an additional email address that you can use within your mailbox. Tuta lets you add five or more aliases in any of the paid versions. You can use these alias email addresses for both receiving and sending secure emails.
Alias email addresses can be set up if you would like several email addresses to be linked to one inbox.
For example, as a private user, you might want to have different alias addresses for different purposes, e.g. youraddress@tutanota.com, shopping.youraddress@tutanota.com, newsletters.youraddress@tutanota.com etc.
As a business, you might want several email addresses for different purposes to go to one centrally managed inbox, e.g. support@yourcompany.com, sales@yourcompany.com, jobs@yourcompany.com etc.
As a family or organization using Tuta, you can set up users for each family member or employee. These users get a separate mailbox, including contacts and calendars, accessible via their personal login credentials.
When you sign up for Tuta, you create an email account. This account initially has a single user which is also an administrator. With any paid subscription, you can add multiple users to your account. As an admin you can manage the users (deactivate a user, change a password or remove a second factor). You may also allow multiple users to be administrators.
To learn how to set up a user or create an alias, watch this YouTube tutorial.
First you need to complete the setup process of your custom domain.
Go to Settings -> Global Settings -> Custom email domains.
Next to each custom email domain is a three dot symbol. When you click it, you can select 'Set a catch all mailbox'. Then you need to choose to which email address and, consequently, to which of your inboxes catch-all mails should go to. This is usually your main admin, but can be any user that you have added to your account.
Once you have set up your catch-all email address, all emails that are being sent to your own domain that do not match any existing email address will be delivered to this catch-all inbox.
Tip: If your domain got leaked to spam lists, we recommend that you set up a dedicated user within your Tuta account for receiving catch-all emails, e.g. catchall@yourdomain.com.
A catch-all email address lets you receive all emails sent to your custom domain – even if the sender mistyped your email address.
In Tuta you can set up a catch-all email address with any paid subscription.
If you have a large number of users, you can import a CSV file containing user name, email address and password. This is useful to automatically create all users in a single step.
To import all users via CSV, you need to create a CSV file with the items 'name', 'email address' and 'password' that contains all users for your company. Then you login with your admin to Tuta and go to 'Settings' → 'User management' → '...' → 'Import Users'
You can then provide the user passwords to the users, so they can log in into their individual mailboxes.
If you can't log in to your account you might be in one of these situations:
Our secure password reset feature allows only you to reset your password. We have no influence on this process. You can read more about this here.
