We are happy to announce that now everyone can use U2F, e.g. a YubiKey, a Nitrokey, or any other hardware token to protect their secure email account. U2F is the most secure form for two-factor authentication as it requires a hardware token to login to your email account.

Secure email login

Your email login is the most important login as for most people your email address is linked to your online identity. Read in our Email Security Guide why securing your email account to the maximum is so important to prevent email phishing.

Here is more information on Tutanota's two-factor authentication, why U2F is the most secure form for 2FA, and how Tutanota encrypts emails, calendars and the address book.

Make sure to write down recovery code

When you lose your second factor, only you yourself can reset your login credential to make sure no one can maliciously take over your account.

It is of utmost importance that you write down your recovery code in case you lose your second factor or forget your password.
