One trick is that you can enroll your TOTP codes on more than one device, the only thing the device need is the clock to be synced to provide the correct code.
You can store your TOTP codes in many places:
That way you don't get caught your pants down if one of your device dies, get stolen, etc. Also, keep the recovery keys / backup keys in a safe place just in case of a worst case scenario.
Keep in mind that your TOTP backup and Password Manager files like KeePassXC can be the weakest link in your OPsec if you're not careful.
Great advice, just want to add that Bitwarden will do TOTP for free if you self-host Vaultwarden.
I thought KeePass files are strongly encrypted. How are they the weakest link if you use a proper pass phrase?
A strong and unique passphrase is indeed really important here, but you need to keep in mind that once the kdbx file is in the attacker's hand, that's the only thing that keep them out.
There's no 2FA, and no throttling on the bruteforce process. So it's really important to use a strong password there to avoid it being the weakest link.
You can kind of do MFA on the database. You can require a key, which can be very long and complex, and you can store it on a USB drive. You might be able to use a key stored on a yubikey or something too, I haven't tried it. It probably depends on which KeePass variant you're using.
I use KeePass with three factors:
Works really well IMO. I use KeePassXC on Linux and KeePass2Android on Android.
I suppose they all use the same challenge-response key?
Yes, unfortunately they need to atm.
