CERTIFIED-IN-CYBERSECURITY Question #443: Real Exam Question with Answer & Explanation
The correct answer is C: SFA uses one authentication method, while MFA uses two or more authentication methods. Single-factor authentication (SFA) is an authentication method that relies on a single factor, such as a password. If you log in to your e-mail account using only a password, this is considered SFA. Multi-factor authentication (MFA), on the other hand, is an authentication method
Question
What is the difference between SFA and MFA?
Options
- ASFA uses two authentication methods, while MFA uses only one authentication method
- BSFA uses one or more authentication methods, while MFA uses two methods
- CSFA uses one authentication method, while MFA uses two or more authentication methods
- DSFA uses two or more authentication methods, while MFA uses only one authentication method
Explanation
Single-factor authentication (SFA) is an authentication method that relies on a single factor, such as a password. If you log in to your e-mail account using only a password, this is considered SFA. Multi-factor authentication (MFA), on the other hand, is an authentication method that requires two or more factors to verify a user's identity. These factors can be a combination of something you know (such as a password), something you have (such as a physical token or smartphone), or something you are (such as biometrics like fingerprint or facial recognition). MFA provides an extra layer of security over SFA. For example, when you log in to your online banking account and are asked to enter a password and provide a fingerprint scan, this is an example of MFA (see ISC2 Study Guide, Chapter 1, Module 1).
