I have been transferring Google Authenticator from phone to phone for years though? Going back to at least 2016, and that was 8 years ago. In 2020 I copied it from Android to iOS even by doing an export I had no idea was there.
It was a manual process requiring the phone to be working, which doesn't help when you have an accident that damages the phone.
The trick is to always put the Auth codes on two devices. One you use, one you safely put away.
