Explanation
Multifactor authentication (MFA) requires verifying identity using two or more distinct factors: something you know (password), something you have (device generating a rotating PIN/TOTP), something you are (biometric), or somewhere you are (location). A password combined with a rotating PIN satisfies two separate factors, making this MFA. RADIUS (A) and TACACS (D) are authentication, authorization, and accounting (AAA) protocols/frameworks that can carry credentials but are not authentication methods themselves. TKIP (B) is a wireless encryption protocol (used in WPA), not an authentication scheme involving passwords or PINs.
