Which of the following is a benefit of using multi-factor authentication?

The benefit of using multi-factor authentication (MFA) primarily lies in its capability to enhance security through the implementation of multiple verification methods. MFA requires users to provide two or more forms of identification before gaining access to an account or system. This typically involves something known (like a password), something possessed (like a smartphone or hardware token), or something inherent (like a fingerprint).

By combining these different factors, MFA significantly lowers the likelihood that an unauthorized user can gain access, even if they are able to compromise one aspect, such as guessing a password. This layered approach to security is effective in mitigating threats such as phishing attacks, since obtaining two or more types of credentials becomes considerably more challenging for attackers.

In contrast, options regarding ease of use with single password access, faster user access, or reduced needs for security awareness training do not reflect the core advantages of MFA, as they do not necessarily enhance overall security measures and may even undermine them if not implemented with proper user awareness and education.
