Cannot sign into google

Had to restore my zte z664c phone to factory default. Tried to sign in to Google with my gmail address. Received message 'This can take a few minutes'...16 hours later, rebooted an tried again. Same problem.

Do you have two-factor authentication active on your Google account?
