Question

Which of the following are fundamentals of MFA?

1) Something you have, such as a one-time pin
2) Something you know, such as a password
3) Something you do, such as a sport
4) Something you are, such as biometrics

Answer 1

The fundamentals of Multi-Factor Authentication (MFA) include something you have (like a one-time pin), something you know (like a password), and something you are (like biometrics). 'Something you do' as presented in the question is not a standard component of MFA.

Step-by-step explanation:

The fundamentals of Multi-Factor Authentication (MFA), which is a security system that requires more than one method of authentication from independent categories of credentials, include:

• Something you have, such as a one-time pin or a security token.
• Something you know, such as a password or a personal identification number (PIN).
• Something you do, like a pattern or gesture, which is generally not considered a fundamental factor for MFA.
• Something you are, such as biometrics like fingerprints, facial recognition, or iris scans.

Items 1, 2, and 4 from the list are correct fundamentals of MFA. They represent the possession factor (something you have), the knowledge factor (something you know), and the inherence factor (something you are). Option 3 (something you do, such as a sport) is not typically considered a fundamental aspect of MFA in the context of cybersecurity.
