Recover after a device becomes out of sync
A device that generates one-time passwords can get out of sync with the OATH authentication service in some cases. If you repeatedly enter valid one-time passwords that appear to be valid passwords, but AM rejects the passwords as unauthorized, your device is likely out of sync.
To resynchronize your device, you must authenticate with a recovery code, and register the device again. Follow the steps in Recover after replacing a lost device.
If you did not save the recovery codes when you registered the device, contact your administrator to remove the device from your user profile instead.
