Hi there. My name is***** see that you've been waiting for help for quite awhile. I'm sorry about that. I'll do my best to help. Authentication usually fails because either the password ***** you have stored on the phone for the Google account associated with the phone is incorrect, or the account has been locked for some reason. Please go to http://www.google.com and try to login using the email address and password ***** the account. If you are unable to login there, you will need to reset your Google password. Once you have reset it, please go into the settings on your phone and change it there as well.
