Nuova Funzione ("Codice di sicurezza") per la 2fa

Hi, I thought it was possible to add the "security code" option to the "2fa" ("Check the two factors").
In practice the "security codes" option is a 4-digit code that can customize the user in case you forget the verification codes (2fa) and also the backup codes (2fa) and also with the telephone SMS you can access that as an alternative.
How about adding this new feature?
