Naše podrobná Nápověda Vám pomůže zjistit vše, co potřebujete vědět o své šifrované schránce.


Přihlášení, zkratky & hlavičkové informace

Tutanota login

  • 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.

Tutanota shortcuts

  • Tutanota supports lots of shortcuts. You can display all shortcuts available in any given section of Tutanota by pressing F1 (fn+F1). You can also use HTML shortcuts to design your mails such as Ctrl+b, Ctrl+i, Ctrl+u.
  • Show header info: You can show the email header of received emails by pressing 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.
Nastavení druhého faktoru (2FA) ve službě Tutanota

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 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 FreeOTP+, andOTP, Authenticator, Authy etc. If setting up a second factor with TOTP fails, please make sure that the time is synced between your devices.
  • 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

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.

Jak si obnovím heslo nebo druhý faktor?

When you create a new Tutanota account, our secure password reset feature empowers only you to reset your account yourself. 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.

In case 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 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 Premium 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 Tutanota 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 Tutanota account with the recovery code.

Přidání vlastních e-mailových domén

If you own one or more domain names that you want to use with Tutanota, you can add these domains to your Tutanota Premium or Pro account. Afterwards you can add email aliases and additional user accounts for your family or company with this domain.

To use your custom email domain, a Tutanota Premium account is required. You can upgrade your existing, free Tutanota account by clicking on "Premium" in the top menu. If you don't have a Tutanota account, you can register here.

After upgrading you are the admin of your Tutanota Premium account. An additional input field will appear under 'Settings' -> 'Global settings' -> 'Custom email domain' where you need to enter your domain. Activate it by confirming the activation button.

This activation process is only successful if you have configured your MX and SPF records for your domain correctly. The MX record is necessary to relay emails for your domain to the Tutanota servers. The SPF record marks the Tutanota server as valid sender of emails from your domain. Additionally, these DNS entries are used to validate that you are the owner of the domain. You need to configure the following DNS records in the settings of your domain name provider:

MX mail.tutanota.de
TXT v=spf1 include:spf.tutanota.de -all

Depending on your domain hoster, it could also look like this:
@ mail.tutanota.de
@ v=spf1 include:spf.tutanota.de -all TXT Record

Please note that changes to your DNS records are not immediately available, but can take a few hours to become active. You can check your DNS settings here.

After you have successfully activated your domain, you can add an email alias or create a user under 'Settings' -> 'User management'.

What do I do if activation fails?

Please verify your DNS SOA entry if the activation of your custom domain still fails. We use the SOA entry for detecting your main DNS server. Therefore, the SOA entry must point to a valid name server.

Jak mohu používat službu Tutanota ve své organizaci nebo firmě s vlastní e-mailovou doménou?
  1. Register a Tutanota Premium account here. This will be your initial administrator account. Once you have added additional accounts to your initial administrator account, you can mark all - or just some - as admin accounts. Your administrator account(s) can configure all general settings and manage user accounts, e.g. reset user passwords. As we at Tutanota can not reset passwords, we recommend to have at least two admin accounts. This way you can reset each others password in case you lose one.
  2. Add your custom email domain in "Settings" -> "Global settings" -> "Custom email domain". There you will also find instructions on how to configure your MX DNS entries first in order to route incoming SMTP emails to the Tutanota email servers.
  3. Add user accounts (i.e. mailboxes) for your domain in "Settings" -> "User management". If you have a large number of users, you can import a CSV file containing user name, email address and optionally the user password. This is useful to automatically create all user accounts in one step.
  4. Provide the user passwords to the users, so they can log in into their mailboxes.

On our business site, there is a summary of all available features of Tutanota's secure business emails.

How to book Secure Connect?

To book the encrypted contact form Secure Connect, you need to:

We recommend that you use Tutanota to secure all your business emails. If you want to use Secure Connect only (without switching email providers), please contact our sales team as the set-up is slightly different.

Journalists get Secure Connect for free. NPOs get the business version of Tutanota at half price which includes Premium, whitelabel and Secure Connect.

How to send an encrypted message via Secure Connect?

When someone starts to communicate with you via the encrypted contact form Secure Connect, the entire communication will be encrypted end-to-end. Encryption takes place locally in the browser so that no third party - not even we as the provider of Secure Connect - can access this information.

Here is how to start an encrypted communication channel via Secure Connect:

  1. Click on Create Request.
  2. Enter a subject line.
  3. Choose a password and repeat the password. In case you want to check for replies later, write down the password somewhere safe.
  4. Enter your message.
  5. Drag and drop files into the message field or click on the symbol in the top right corner to attach files. They are automatically attached to the message.
  6. In case you want to be notified about replies, enter an email address at the end. This is optional. If you want to stay anonymous we recommend not entering an email address here.
  7. Click on Send in the top right corner.
  8. A random email address for your encrypted communication channel has been created. Write down this email address (and the previously chosen password) to re-access your encrypted communication channel later.

While sending the encrypted message via Secure Connect, Tutanota automatically creates a mailbox for the sender with an automatically generated email address of your custom email domain. The sender can login with the selected password to read your reply and also reply again. With Secure Connect an encrypted communication channel has been established that is both easy to use and secure.

Kdy potřebuji zašifrované e-maily?

Email encryption is needed whenever you want to send a confidential email. That is whenever your emails 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 Tutanota.

Alice is registered with Tutanota, Bob may be registered with Tutanota or an external recipient and Carol is not registered with Tutanota. In any case all emails (including attachments) are stored encrypted on the Tutanota servers. Independent of the end-to-end encryption, the transport between client and Tutanota servers is secured with SSL and DANE to maximize security. You can check here how to install the DANE browser add-ons.

Sending and receiving end-to-end encrypted emails
The email is encrypted on Alice' client, stored encrypted on the server and can only be decrypted by Alice or Bob.

Sending and receiving end-to-end encrypted emails

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.

Sending non-confidential emails

Receiving non-confidential emails
When the SMTP email is received by the Tutanota server, it is encrypted for Alice and then stored on the server.

Receiving non-confidential emails

Instrukce na aktualizaci WebView v systému Android

Updating WebView is usually as simple as installing an app. For devices with Android older than N (7), this is usually the app called Android System WebView, which you can download from the PlayStore here.

Additional optional settings changes

The Android N default WebView is usually tied to the Chrome browser. If you don't want to install Chrome, you can install another provider and later select another WebView implementation in the developer settings.

To enable developer settings:

  • Open up your Settings app.
  • Scroll all the way down to find “About Phone” (or “About Tablet”)
  • Scroll down again and find the entry with the Build number.
  • Start tapping on the “Build number section”, Android will now pop up a message informing you that in x amount of clicks you will become a Developer. Keep tapping until the process is complete.

Some of the apps providing WebView are:

Note for LeEco device owners: LeEco made changes to some devices which prevents changing WebView. We don't know of a workaround, yet. We recommend using the web browser to access your Tutanota mail account.


Rozcestník: E-maily a složky

V závislosti na šířce vašeho prohlížeče, Tutanota zobrazí váš seznam složek, váš seznam mailů a vybraný mail.

![Složky s poštou] ({emailImageLink})

  • Pro přidání složek, klikněte na symbol 'plus' vlevo v seznamu složek. Zobrazí se vyskakovací okno, do kterého zadáte název. Nově vytvořená složka bude zařazena abecedně v seznamu složek. Můžete přidat tolik složek, kolik potřebujete.
  • Pro pozdější editaci složky na ni klikněte. Potom klikněte na symbol třech teček vedle názvu složky. Složku můžete 'Přejmenovat' nebo 'Smazat'.

Sending of emails

Write a mail

Condensed email window.

  • Click on the red pen symbol in the down right corner to compose a new email.
  • When you enter an email address into the 'To'-field, Tutanota shows you the preview of matching email addresses from your address book. You can hit 'Enter' to choose the first email address shown or you can keep on typing.
  • Once you have entered an email address in the 'To'-field, the 'Confidential'-button appears in the 'Subject' line. Click on it to send this mail not end-to-end encrypted. You may also switch the default to encrypted/not-encrypted here in your Settings→ 'Default delivery'.

Writing an email

Enlarged email window.

  • Click on 'Show' in the 'To' field to enlarge/reduce the options shown. After enlarging it, you can enter Cc- and Bcc-recipients.
  • If you have added an alias in 'Settings', you can also change the email address you want to send from by clicking on the pen symbol next to the 'Sender' email address. You can change the default sender here in your Settings→ 'Default sender'. This makes your alias the default sender, the Tutanota address will still remain the main account address (name in tab) which can't be changed.
  • External recipients of an end-to-end encrypted email receive a notification mail from your Tutanota email address. You can choose the language of this notification email by clicking on the pen symbol on the right (in this screenshot: English is chosen).

Text editing tools

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 Tutanota 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.

Výchozí zasílání nešifrovaných e-mailů

Go here in your Settings. You can choose whether emails to external recipients should be encrypted by default ('Confidential') or if you need to click on the lock symbol when composing an email to encrypt it ('Not confidential' = unencrypted by default). Emails to other Tutanota users are always encrypted by default.

Šifrovaný e-mail externímu příjemci

Při odesílání šifrovaného e-mailu externímu příjemci musíte při vytváření e-mailu zadat heslo.

Writing an email

Po nastavení se heslo automaticky uloží spolu s kontaktem v adresáři Tutanota. Při dalším e-mailu na tohoto příjemce jednoduše zadejte e-mailovou adresu a Tutanota automaticky zadá heslo. Heslo je třeba zaslat protistraně jiným komunikačním kanálem.

Externí příjemce

  • obdrží e-mail s odkazem na Tutanotu (otevře se prohlížeč),
  • zadá vámi zaslané heslo,
  • může číst automaticky dešifrovaný e-mail, důvěrně odpovědět, vyexportovat všechny vyměněné zprávy a uložit je u sebe.

Poznámka: Odkaz v e-mailu s upozorněním obsahuje kód, který je potřeba k dešifrování spolu s heslem. Takže někdo, kdo chce zachytit šifrované zprávy, potřebuje přesný odkaz a heslo. (Starý odkaz se deaktivuje, jakmile pošlete nový e-mail na stejnou e-mailovou adresu.)

Přidávání aliasových e-mailových adres

As a Premium or Pro user, you can add aliases to your account. You can also add additional alias packages. Refer to our pricing page for details.

Go here in your mailbox→ 'Email aliases': Click on 'Show Email Aliases'. Click on the plus symbol to add aliases. A pop-up opens where you can type the alias you want to add. Click on the three-dot button to choose the domain for your alias. This can be any of the Tutanota domains or of your custom email domains that you have added to your Tutanota account.

Please note: Aliases with a Tutanota domain can only be disabled, but not removed. Deactivated aliases must remain linked to your account in case you want to activate them again in the future. When you are using your own domain with Tutanota, you can delete aliases with your custom email domain and create new ones.

You can change the default sending address to your own domain alias (or any other alias) by changing the default sender here in your mailbox→ 'Default Sender'. This will make your alias the default sender. However, the main address of your Tutanota account (name in tab) will remain unchanged.

Pravidla detekce spamu (konfigurace whitelistu a blacklistu spamu)

Spam detection in Tutanota is multi staged. For incoming unencrypted SMTP emails the received email is checked against DNS blacklists 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 (blacklist) or explicit not as spam (whitelist). 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 Tutanota account you can configure the email address list here in Settings.

Please click on the sender's address to assign the email address or domain with one of the following spam rules:

  • No spam - Emails from this sender email address are always stored in the inbox.
  • Always spam - Emails from this sender email address will always be stored in the spam folder.
  • Discard - Emails from this sender email address will be silently discarded. The sender does not get any information about it.

The "No spam" rule has a higher priority than "Always spam" and "Discard" has the lowest priority. Furthermore you are able to define rules based on a domain instead of a single email address. Rules defined for a domain have a lower priority than rules for an email address.

Rules for domains are restricted. You are not able to assign the rules "Always spam" and "Discard" to Tutanota domains, neither to your custom domains.

Activate whitelabel automatic

Activate whitelabel manual

  • 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. Create the subdomain by setting the CNAME DNS entry for that domain to point to login.tutanota.com at your domain hoster. The DNS entry should look like this: ' CNAME login.tutanota.com'. Depending on your domain hoster you might have to set the fields 'name' to '', 'type' to 'CNAME' and 'value' to 'login.tutanota.com'. Keep in mind that the DNS changes may take a while until propagated.
    • Enter this subdomain under 'Whitelabel domain'.
    • 'Certificate type': Click on the pen symbol and choose 'Automatic (Let's Encrypt)'. Certificates for your domain will be issued and updated automatically.
  • 'Certificate type': Click on the pen symbol and choose 'Manual'. You need to get and update certificates for your own domain manually.

    • 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 encoded). 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.

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

  • 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.
