How to fix Google Authenticator on Android

If you are experiencing trouble with your Google Authenticator code and you are using an Android phone, it might be because the time on your Google Authenticator app is not synced correctly.

To make sure that you have the correct time, carry out these steps:



  • Launch the Google Authenticator app
  • Go to the main menu
  • Tap Settings
  • Tap Time correction for codes
  • Tap 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 on your Android phone, and will not change your device’s Time and Date settings.
