Authenticator App
You can set up the Two-Factor Authentication (2FA) using the Google Auth that use a 6-digit code generated by an app every 30 seconds, this means that at every logging you will have to enter a code provided by an app that has been downloaded previously and you will be prompted to enter it or to scan a QR code in order to login to your cockpit.
For this please go in menu "My Account -> Two-Factor Auth" and then click on "Add a new Authenticator App".
A new window will be prompted, you can indicate a friendly title for this 2FA method (you will see it when logging in so don't put any secrets in it). Then you have to indicate if this should be the default 2FA when you log in to the site, we recommend to tick this option.
