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.

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!

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.
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.
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.
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.
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 firstname.lastname@example.org. 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.
If you would like to report abusive usage originating from another provider's email address, you can find contact addresses at abuse.net.
