I keep a backed up list of all my 2fa codes in a password/key encrypted storage. I am trying to avoid the kind of situation you described. I have A LOT of accounts with 2fa now, and losing access to the 2fa app would be an incredibly frustrating issue as I would lose access to many accounts. At one point I actually had a couple backup codes for some important accounts in my wallet, such as to my email. My thinking was that if I ever lose my phone and need to login to my Google account on someone else's device I would at least have access to some backup codes to get me in ASAP.
