Which of the following is an example of multi-factor authentication for PC security?  

Key Points

• A fingerprint scan is an example of multi-factor authentication (MFA) used to enhance PC security.
• MFA requires two or more verification factors to gain access to a resource such as an application or online account, improving security by combining something you know (password) with something you have (security token) or something you are (biometric verification).
• Using a fingerprint scan adds an additional layer of security as it is unique to each individual and difficult to replicate.
• Other examples of multi-factor authentication methods include facial recognition, one-time passwords (OTPs), and smart cards.

Additional Information

• Antivirus software is primarily used to detect and remove malware, but it does not constitute multi-factor authentication.
• OS protection refers to security features built into the operating system, such as user account control and encryption, but it is not MFA.
• Firewall protection helps to block unauthorized access to a network but does not involve multiple factors of authentication.
• Implementing MFA is a critical step in securing sensitive information and preventing unauthorized access to systems.
