I'm choosing option to add MFA in the Google accounts, scanning barcode, secret is added. Name of the account in the Authenticator is correct. However, when I try to enter the generated code - Google says it's incorrect. The same on all attempts.
Ideas?

UPD I've tried syncing time from the Authenticator - still getting errors

UPD2 Can it be the reason that I previously had Authenticator installed on another phone with different email?

  • I'm having the same issue. I synced the time and that didn't help. I uninstalled, reinstalled and reconnected the app, and that didn't work either. The device time is correct. I'm not sure what else can be done. – Mark Cramer May 1 '15 at 0:22

Have you tried the following (taken from Google Authenticator site:

My Google Authenticator codes aren’t working (Android)

This might be because the time on your Google Authenticator app is not synced correctly.

To make sure that you have the correct time:

  1. Go to the main menu on the Google Authenticator app
  2. Click Settings
  3. Click Time correction for codes
  4. Click Sync now

On the next screen, the app will confirm that the time has been synced, and you should now be able to use your verification codes to sign in. The sync will only affect the internal time of your Google Authenticator app, and will not change your device’s Date & Time settings.

  • Yes, I have. No results. – user626528 Aug 26 '14 at 9:38
  • ah. just seen you've updated your answer to say you've tried this. I'll leave it here but update it if I find anything else that might help. – bmdixon Aug 26 '14 at 9:38
  • Have you checked your device time to ensure it is correct (even a few minutes may affect it). Can you try using authy and see if that works. It's another app that does the same as the Google Authenticator app (Should work exactly the same) – bmdixon Aug 26 '14 at 13:24
  • time is absolutely precise. Is it safe to use this 3rd part application? – user626528 Aug 26 '14 at 15:23
  • It is a popular alternative to the Google authenticator app, it has between 100,000-500,000 installs and has good reviews. I don't use it myself but it appears to be a good app. I can't promise that it's 100% safe though in the same way I can't guarantee any app is safe. – bmdixon Aug 26 '14 at 15:27
