Often with setting up 2FA by TOTP you also get a list of backup codes, it would be nice to have the ability to add them to the password layout. Possibility the ability to past the list and they become an array where if you use one it can be removed from the array. Right now I see a lot of people adding them to the notes field which is far less secure (I know even more secure would be to not store them in the same place as the TOTP/Password but it's a start!)
