With Google Authenticator some years ago it wasn't even possible to restore your codes even if you had a local backup of the device. I'm not sure if that still is the case today but it was a common issue which we saw at our service desk before we switched to a different solution.

Yeah I had to re-enroll my phone when I got a new one a few years ago.

I never did get around to doing all of them so I still have the old phone in a drawer for those rare times I need it.
