Support TOTP and FIDO2 Authentication

Hi, as requested by other users please support better two step verification methods such as TOTP apps such as Microsoft Authenticator, Google Authenticator, Yubico Authenticator etc. As a better method please support FIDO2 authentication for hardware security devices such as YubiKeys. At present Phone based authentication is vulnerable to SIMS cloning and relying on just an email address for authentication is poor practice.
