Name two authentication methods aside from passwords and a scenario for each.

• A. MFA using an authenticator app; biometrics such as fingerprint for access.
• B. Passwordless login using magic links
• C. Smart cards and hardware tokens
• D. Security questions and CAPTCHAs

Answer: (A)

Two authentication methods beyond passwords are using an authenticator app for multi-factor authentication and using biometrics like fingerprints. Using an authenticator app adds something you have as a second factor. When you sign into a service from a new device, you don’t just enter a password; you confirm a code or a push notification from the app on your phone. This proves you possess the device with the authenticator and ties the login to you, making it much harder for someone to gain access with just a stolen password. Biometrics adds something you are. A fingerprint, facial recognition, or another unique physical trait verifies your identity quickly and conveniently. For example, you might unlock your laptop or approve access to a banking app with a fingerprint. Since these traits are difficult to imitate, they strengthen security while keeping the login user-friendly. Other options either rely on a single method or on weaker factors, so they don’t provide the same level of protection or require a second distinct factor in the same choice.
