Which of the following is a benefit of using Multi-factor Authentication (MFA)?

1. It simplifies user experience

2. It adds an extra layer of security for user accounts

3. It eliminates the need for passwords

4. It automatically updates user roles

The correct answer is: It adds an extra layer of security for user accounts

Using Multi-Factor Authentication (MFA) adds an extra layer of security for user accounts, which is its primary benefit. MFA requires users to provide two or more verification factors to gain access to their accounts, rather than relying solely on a username and password. This significantly enhances security, as even if a malicious actor manages to obtain the user's password, they would still need the second factor (such as a one-time code sent to the user's mobile device) to gain access. This added layer protects user accounts from unauthorized access, particularly in the face of common security threats like phishing attacks or credential theft. In contrast to this, simplifying the user experience is not a primary goal of MFA, as it often introduces additional steps for users. Moreover, while MFA enhances security, it does not eliminate the need for passwords altogether, as users must still have a password in most cases for the authentication process. Furthermore, MFA has no role in automatically updating user roles, as that function relates more to identity and access management policies rather than authentication mechanisms.
