8-digit backup codes for Gmail

Djoe -  
Hello, I have a problem with my Gmail address. I have the code, but I'm being asked for an 8-digit backup code (Backup-codes-username.txt). I've entered all of them, and none of them work. Thank you in advance ????????????

    Good evening,
    My Google Authenticator codes are not working

    It is possible that the time is not correctly synchronized in your Google Authenticator app.

    To set the correct time, follow these steps:

    On your Android device, go to the main menu of the Google Authenticator app.

    Tap on More then Settings then Time correction for codes then Sync now.

    On the next screen, a message will confirm that the time has been synchronized in the app. You should be able to log in. The synchronization only applies to the internal time of your Google Authenticator app. The date and time of your device are not modified.
