Google Authenticator does not work on my Android, how do I fix it?
If the Google Authenticator codes do not appear to work when you're logging in, check that your Android device's clock is accurate, or that another app installed on the phone has not caused a clock delay.
Simply rebooting the phone may resolve the problem, or disabling Google Authenticator for your account and then re-enabling it may also help.
