the lock screen because its hidden and you need to try the Alternative password for a few times until the “Unlock via Google” option appears.
It generally needs a minimum of 5 trials and fails for the Alternative password
before you go back to the lock screen and see the Google unlock option.
You have two options:
Delete all fingerprints (by going into settings & long pressing on the finger print, selecting remove) and recreate them. This will also clear you alternate password.
Go to Android Device Manager
