• Here you login to our mail client.
• Please enter your full email address and password and click login.
• If you tick 'Store password', your password will be stored in the browser for easier login. Only choose this option if you are using your own device.
• Click on 'More' to see more options. 'Sign up' to register a new account and 'Switch color theme' to switch to the dark theme (shown in the screenshot above).
• If you have saved your password, you will see two more options under 'More': 'Different account' to login with another Tutanota email address and 'Delete credentials' to delete the password you have previously saved in the browser.

• Show header info: You can show the mail header by pressing Ctrl+h.
• Tutanota strips headers from emails sent to protect your privacy.
• If the technical sender is different from the header info, Tutanota warns you about this. The differing sender information could be a sign that this mail is coming from a scammer.

It is not required to set up 2FA on your account, but it is recommended if you'd like the peace of mind that comes with the additional security.

Registering your second factor

You can connect your second factor with Tutanota in "Settings" -> "Login". As admin you can setup second factors for your users in "Settings" -> "User management".

Tutanota currently supports the following second factor types:

• Security keys (U2F), e.g. Yubikey. U2F is currently supported by Chrome and Opera.
• TOTP with an authenticator app such as Google Authenticator, Authy etc.
• We plan to support more second factor types. Please let us know via social media which ones you prefer!

Second factors can be added by administrators and "normal" users, but removed only by admins.

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 and additionally 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. Instead, 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

You can reset the second factors if you have noted down your personal recovery code. 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.

When you setup a new account, please make sure that:

• You write your password down and keep it somewhere safe.
• You write down your recovery code to never lose access to your Tutanota account.

When it is already too late and you can't login to Tutanota, please make sure that:

• You have entered your email address with the correct ending, e.g. ".de" or ".com"
• The caps lock key is disabled
• The time on your TOTP device is synchronized correctly (only applies if second factor authentication with TOTP fails)

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 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 be make sure to never lose your Premium account, it's best to have at least two administrators.

Recovery code is available

Did you write down your recovery code? If so, 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 innovative reset feature on our blog.

I can proof that I am the owner of the account

Are you able to proof that you are the owner of the mailbox? We can move your original mail address as an alias to a new account. You will be billed 30 € for the mail address transfer to a new account, as this involves manual effort from our support staff. You also need to create a new Premium or Pro account.

Contact us and include the following details to prove that it is your account:

• Email address of your original account
• Creation date of your original account
• Date of last successful login to your original account
• Date of last transaction of your original account (only for paid customers)
• Email address of your new Premium account

• 'Whitelabel domain': Click the pen symbol to activate the whitelabel feature for your own domain. A pop-up shows up where you have to enter the following information (shown in the screenshot):

• Choose a subdomain of your own domain, at which you would like to reach the Tutanota login. This must be a subdomain, a main domain is technically not allowed. Set the CNAME DNS entry for that domain to point to login.tutanota.com. Keep in mind that the DNS changes may take a while until propagated.
  • Upload your domain's SSL certificate chain and
  • your domain's private key to enable the Tutanota login at your domain. Both must be provided in PEM format (base64 coded).
  • 'Custom logo': Click the pen symbol to upload your logo. It will be shown in the top left corner (38x280 pixel) when you load Tutanota at your own domain.

• 'Custom colors': Click the pen symbol to set the colors according to your own corporate design. If you don't set a color, the default color from the Tutanota style sheet will be taken.
• 'Custom meta tags': Click the pen symbol to enter a meta tag.
• Now you can open your custom domain in your browser and see the Tutanota login with your own logo and own colors.

When you order the whitelabel upgrade for your Premium account you can activate the Tutanota login on your own domain (a sub-domain), change the look of Tutanota according to your needs (e.g. corporate identity) and create contact forms for your clients. If you send confidential messages to external recipients, those recipients are also directed to your whitelabel domain.

Complete list of possible customizations:

• Set custom logo (displayed on your whitelabel domain instead of the Tutanota logo)
• Set custom colors (displayed on your whitelabel domain)
• Set custom meta tags for the Tutanota app on your whitelabel domain, like title and social media texts
• Set a custom imprint link (displayed in the "More" menu on the login page of your whitelabel domain instead of the Tutanota imprint link)
• Set a custom notification email text for external recipients (coming soon).

Preconditions for applying the whitelabel feature:

• You need your custom whitelabel domain. This must be a subdomain. A main domain is technically not allowed. It is also not allowed to add an email domain as whitelabel domain.
• You need a valid SSL certificate for your whitelabel domain and you need to make sure to update it in Tutanota before it expires.

This is how you can setup your whitelabel domain:

1. Choose a subdomain of your own domain, at which you would like to reach the Tutanota login.
2. Set the CNAME DNS entry for that domain to point to login.tutanota.com. Keep in mind that the DNS changes may take a while until propagated.

3. Enable the Tutanota login at your domain by uploading your domain's SSL certificate chain and private key here in your Tutanota Settings - Whitelabel. Both must be provided in PEM format (base64 coded). The private key file content must start with the line "-----BEGIN RSA PRIVATE KEY-----" or "-----BEGIN PRIVATE KEY-----". The certificate file content must start with the line "-----BEGIN CERTIFICATE-----". In order to create a certificate chain from individual certificates create a file in a text editor. Then first copy your domain's certificate into that file and below that certificate any intermediate certificate or certificate bundle that was provided to you in addition to you certificate file. Your certificate chain file might then look like this:

   -----BEGIN CERTIFICATE-----
   (Your SSL certificate, e.g. from your_domain_name.crt)
   -----END CERTIFICATE-----
   -----BEGIN CERTIFICATE-----
   (Your intermediate SSL certificate, e.g. from intermediate.crt)
   -----END CERTIFICATE-----

4. Optionally upload your custom logo to be shown when you load Tutanota at your own domain.

5. Optionally configure your custom colors to be used in Tutanota when you load Tutanota at your own domain.

Now you should be able to open your custom domain in your browser and see the Tutanota login with your own logo and own colors. Additionally you may now order and setup contact forms ("Settings" -> "Contact forms") which allows you to be contacted confidentially.

Please note that your whitelabel customizations will not be visible in the mobile apps.

Contact forms allow you to be contacted confidentially as all messages are automatically end-to-end encrypted.

Create a new contact form

• Click the plus symbol in the down right corner. A pop-up shows up which lets you create a new contact form.

• 'Receiving mailbox': Click the user symbol (left) to select one user who should receive all emails sent via the contact form.

• Click the delete symbol to delete this contact form.
• Click the Export button further down to export a CSV log of all contact form requests in a given period of time.

• The global admin can create a local admin group to add as well as manage administrators of users and contact forms. Please refer to 'Create a local admin group' for details.
• The user who creates another user or contact form becomes the administrator of the created entity. More precisely, the admin group in which the user is member will become the admin of the entity. If the user is a global admin, then the entity is administrated by the global admins. If the user is a local admin (i.e. member of a local admin group), then that local admin group becomes the admin.
• The global admin can change the administrator of a user by selecting a local admin group under 'Administrated by'.
• Local administrators only see those users and contact forms that they administrate.
• Even if an entity is administrated by a local admin group, the global admins can still administrate the entity.
• A contact form is always administrated by the administrator of its receiving mailbox. So if a global admin changes the receiving mailbox of a contact form, the admin of this user mailbox becomes the administrator of the contact form.
