What is one key feature of multifactor authentication?

1. Username and password only

2. Requires only something you know

3. Combines two different forms of verification

4. Access based on user roles

The correct answer is: Combines two different forms of verification

Multifactor authentication (MFA) is a security mechanism that enhances the protection of user accounts and sensitive data by requiring two or more distinct forms of verification before granting access. This approach significantly reduces the risk of unauthorized access, as it relies on multiple factors that an attacker would need to compromise. The combination of different forms of verification can include something you know (like a password), something you have (such as a smartphone or hardware token), or something you are (biometric data). By requiring two or more of these factors, MFA creates a robust security barrier that makes it much more challenging for malicious actors to gain access to an account or system. In contrast, the other options do not reflect the multifactor aspect of authentication. Relying solely on a username and password does not provide the layered security that MFA offers, making it less secure. Furthermore, requiring only something that you know simplifies the authentication process to a single-factor approach, negating the benefits of multifactor authentication. Access based on user roles, while important for managing permissions, does not pertain to the process of verifying user identity through multiple forms of evidence.
