Explanation

Two-factor authentication (2FA) requires two distinct factor types from: (1) something you know (password, PIN), (2) something you have (hardware token, smart card), or (3) something you are (biometrics). A hardware token (A) is 'something you have' - a physical device generating a one-time code. Biometrics (D) is 'something you are' - fingerprint, face recognition, etc. Username and password (E) is only a single factor category ('something you know'). OAuth (C) is an authorization protocol, not an authentication factor. WebView2 (B) is a Microsoft browser rendering component with no role in authentication.
