The codes from my authentication App are invalid

Authentication apps such as Google Authenticator use the current time when generating codes.
These codes are valid for a short period of time (typically shown as a countdown or clock timer), after which they become invalid and are replaced by a new code.

If your codes are not working correctly, please check the system clock on your computer or smart-device, ensuring it is working as expected as this can cause invalid codes to be generated.
Ideally, try enabling the option in your device settings to automatically update the date/time where available.

If your codes continue to report as invalid, please Remove Login Verification, and then Reapply Login Verification to see if this rectifies the problem.
