To enable 2FA for your HostMantis client area account:
Log into our client area: https://my.hostmantis.com/clientarea.php
Click on "Hello (Your Name)!"
Click "Security Settings"
In "Two-Factor Authentication", click "Click Here to Enable"
Please note, during enabling 2FA, you will be given backup codes.
These backup codes are vital and should be documented and kept in a safe place.
Should you lose your phone or device that was used to enable 2FA, you will need the backup codes to recover.
Without the backup codes there is no way to recover the account!
