Facebook: Activate two-factor authentication

To make your Facebook account as secure as possible, you can activate two-factor authentication. Now you have to enter another security code each time you log in from an unknown browser or PC.

Adjust settings for two-factor authentication

1. First open the settings menu via the "Privacy shortcuts" (lock symbol in the upper right corner) and "Show more settings".
2. Under the "Security" menu item you will find the "Registration confirmation" option.
3. Activate this by ticking the option.
4. If you have not yet entered a mobile phone number in Facebook, you will now be asked to do so.
5. After a short time you will receive the first confirmation SMS. Enter the code contained in the window on Facebook.
6. Your two-factor authentication is now activated in Facebook.

You can also enable two-factor authentication on Yahoo or Twitter. We will show you how to do this in further practical tips.
