Don't freeze the controls after less than 3 unsuccessful login attempts
When logging in or unlocking, if I enter an incorrect password, all the controls are frozen for a short while and a spinner is shown. This forces me to wait before I can re-enter my password.
This behaviour is frustrating. It's not uncommon to mistype a password, and it's annoying to have to wait.
The latest unlock/login designs suggest only having a delay after 3 unsuccessful login attempts.
