One of the risks of 2FA is losing access to your accounts after losing the authenticating device. Backing up the 2FA seeds mitigates that risk. The backup needs to be encrypted with the password remembered and stored somewhere. Sounds like it’s a job for a password manager, preferably in an offline local password manager with a different database. |

A "2FA Mule"[1] solves this problem by staying in one place with constant power.
I receive plain old SMS 2FA codes while flying in an airplane.
I also don't care that much if I lose or destroy my personal mobile. In fact, I don't even know my current SIM number. If I lose my personal mobile I just edit a twiml bin at Twilio and point my number somewhere else ...
