At the moment Superform v2 2FA is limited to TOTP via apps like Google Authenticator or Microsoft Authenticator, which depend on mobile devices and carry risks like theft or compromise.

I propose add FIDO2/WebAuthn support for hardware keys (e.g., YubiKey, OnlyKey, Google Titan, Ledger etc) via USB, NFC, or Bluetooth. This upgrade will improve security and user options.
