Which of the following is an example of multi-factor authentication for PC security?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Fingerprint scan.
Multi-factor authentication (MFA) enhances PC security by requiring multiple forms of verification. An example is logging into a computer using a password (something you know) and a fingerprint scan (something you are). This combination ensures stronger security compared to single-factor authentication. Another example includes using a smart card (something you have) along with a PIN (something you know). MFA reduces the risk of unauthorized access by making it difficult for attackers to bypass all authentication layers, thereby strengthening overall cybersecurity and protecting sensitive data effectively.
