At this point, I'm used to MFA for stuff (and I use a password manager
that handles 2FA OTPs too), but the Fedora implementation of MFA is
uniquely bad because we have to do a lot in the terminal, and our MFA
implementation sucks for terminal usage.
If MFA is turned on:
1. The Fedora account integration in GNOME breaks
2. You need to concatenate password and OTP for getting a krb5 session ticket
3. The recovery mechanism involves GPG signed emails
The experience using 2FA for Fedora accounts is sufficiently
unpleasant that I really don't want to use it.
Thank you, these are valid points that I was mostly unaware of.
