With two-factor authentication, you have to confirm each subsequent login with an additional code. You will receive the code by email (soon it will also be possible to receive this code by text message).

Two-factor authentication protects your account from unauthorised access in addition to the password. Activating and deactivating 2FA requires you to enter your current password.

How to enable two-factor authentication

Go to Settings > Security, select two-factor authentication and activate it. In the following window you have to enter your e-mail address that will be used to send the code to.

After you click on 'Apply', you must log in with the additional code the next time you log in.
