If you use Google 2fa authentication app you probably should turn OFF the sync to cloud option

sidenote:
you should enable google prompt
When you sign in to your Google Account via a new device you get a full screen alert notification on your main device(smartphone), you can tap that notification on your phone to confirm it's you or deny which will stop the sign in attempt - Google prompts give you info about the device, location, and time of the sign-in attempt.
enable it via your google account security 2fa
having google prompts enabled still allows you to to use 2fa app
