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 Identity Cloud 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.
