For crucial stuff, I take photos first and store them on my own nextcloud (with its own replication) and also copy them on a physical device. And my Android authenticator (andOTP) allows me to export encrypted backups (with password saved on password manager, ofc), which I then save on Dropbox.

If it's a MFA I actually don't care much about (security-wise), I simply save the token on bitwarden so it autocompletes for me (it defeats most of the main point of "multi" FA but I don't care about it to begin with).

Printing is not a bad idea, especially for backup, if you put them in a fire-proof safe or something. Make sure to give each a name to know which service they are for.
