Remind HN: Make Backups for 2FA

My phone died unexpected yesterday morning (unrecoverable random hardware failure). This means that if I hadn't bothered to make backup codes a few years ago for my google account, I would have been locked out of signing in through the authentication app (installed only on my phone) and through text-based authentication codes, because I use project fi and I don't have another compatible phone that I could put my sim card in.

Just a reminder of the frustrating situations that some of you might find yourself in if you use 2FA the same way I do.
