You can restore access to the Admin Area or Client Area after the loss of a two-factor authentication (2FA) device and backup code.
If users or admins lose their two-factor authentication (2FA) device, they can regain access to WHMCS using their 2FA backup code.
After you enable two-factor authentication (2FA), you can require users and admins to configure it the next time that they log in to WHMCS.
