I should probably have clarified - I don't actually use the phone as a backup for 2FA through SMS. That would probably require porting the number if something happened to the first phone, or setting up 2 seperate SMS 2FA methods on every account (where that is even possible). Also, I hate SMS 2FA. I think of the 2nd phone as basically just a little portable computer with Bitwarden, and on which I could probably use some sort of messaging app or email while I replaced the first phone. Yubikey is the popular answer so far. I have thought of that in the past, but never followed through on. Less versatile (can't run apps)? Certainly more portable.
