You will be prompted for your Group-Office password. Next you will be asked to scan the QR code with your app to register Group-Office. Enter the code from the phone to confirm you’ve set it up and you’re done.


While this module is called Google authenticator it doesn’t need a Google account. It does not interact with Google when logging in in any way.
