My fingerprint scanner will not work today and it will not let me log into my google account it claims password is in correct yet i can log onto google account on another device.
Welcome to Android Central! Which phone? If the scanner isn't working, then it's asking for the backup password you created when you first set up fingerprint unlock. That password is different from your Google password. Do you remember it? Fingerprint sensors are not 100% error-free, which is why it's so important to remember these backup passwords.
