There are redundancy systems to avoid getting locked out of 2FA.
- 1st Backup Codes: Store a bunch of 2FA backup codes on a safe location, best not in YOUR home, in case it burns down.
- 2nd SMS verification: some services offer you a fallback to SMS in case you don't have your 2FA device with you. But keep in mind, that SMS is also one of the least secure 2FA methods.
- 3rd instead of having your auth codes only on one device, use a service for it like Authy, so you can install it on as much devices as you like, if one dies, it's easy to configure a new one.

Isn't this a common complaint that SMS fallback cannot even be turned off? People say SMS is not secure enough so they switch to something better, but all the services do SMS fallback anyway so what is the point of using the more secure one?
