If you have 2FA activated for your company's account in CtrlPrint and have received a new phone you will need your token reset by an administrator. (This is someone at your company or your agency partner and not someone at CtrlPrint.) This will allow you to rescan the QR code and sync your account with your new phone.
Your administrator will need to log in as an admin in the system, locate your user account and click on the option called "Reset 2-Step verification". The next time you log in you will be presented with a new QR code to scan.
If you are unable to contact an administrator you can send a request to support@ctrlprint.net (from the email address associated with your CtrlPrint account) requesting your 2FA token to be reset.
