Why is multi-factor authentication critical for helpdesk security?

• A. It makes passwords longer.
• B. It adds a second verification factor, reducing credential theft and unauthorized access.
• C. It eliminates the need for passwords.
• D. It only applies to administrators.

Answer: (B)

Multi-factor authentication strengthens access by requiring a second verification step beyond a password. Even if a password is stolen or guessed, the attacker still needs the additional factor—like a code from a mobile authenticator, a hardware token, or a biometric check—so unauthorized access is much less likely. This is especially important in a helpdesk context, where credentials are used across many systems and attackers often try stolen credentials to impersonate users. It’s not about making passwords longer or eliminating passwords entirely; it’s about adding a separate, harder-to-procure factor. And MFA benefits all users, not just administrators.
