I can't seem to find an answer online to solve this... I have an account for which I set up 2 step verification, using Google Authenticator on my iphone to generate the verification code. Today I tried to sign in to the account, then opened Authenticator, and instead of giving me a code as it should, Authenticator went to a setup screen as if it were a new install. Seems like the solution would be to set up the app again, but when I go to my Google account to do so, there is no longer an option to use Authenticator as the 2 step verification method, so I can't find any way to complete the setup of Authenticator. And, I can't get into the account I am trying to access because it wants the Authenticator code and doesn't offer me any alternate way to log in without that code. Any ideas on what I can do to re-enable Authenticator?
