Which statement is true regarding multifactor authentication?

• A. It requires only a password for access.
• B. It simplifies the user login process.
• C. It strengthens security by requiring multiple verification methods.
• D. It is used only for sensitive applications.

Answer: (C)

Multifactor authentication enhances security by requiring multiple verification methods before granting access to a system or application. This approach typically combines something the user knows (like a password), something the user has (such as a smartphone or physical token), and something the user is (biometric data like fingerprints or facial recognition). By employing several distinct factors, multifactor authentication raises the bar for potential attackers, making unauthorized access significantly more challenging.

While options discussing simplicity or exclusivity to sensitive applications may appear attractive, they do not capture the core essence of multifactor authentication. The primary strength of this security measure lies in its ability to reduce the risk of breaches through layered defense mechanisms.
