Consider the following statements regarding Multi-Factor Authentication (MFA) and cryptographic principles: I. Two-Factor Authentication (2FA) requires combining two distinct verification factors, typically something you know (password) and something you have (security token or authenticator app). II. Time-based One-Time Passwords (TOTP) are highly dynamic and typically change every 30 or 60 seconds to maintain robust security. III. Cryptographic hash functions like SHA-1 or SHA-256 are commonly utilized within the HMAC-based algorithms to generate secure short codes in TOTP systems. Which of the statements given above are correct?
