Identify a key benefit of using multi-factor authentication (MFA).

A key benefit of using multi-factor authentication (MFA) is that it adds an extra layer of security beyond just passwords. By requiring a combination of two or more verification factors—such as something the user knows (a password), something the user has (a mobile device or token), or something the user is (biometrics)—MFA significantly increases the difficulty for unauthorized users to gain access to accounts and sensitive data. This multidimensional approach greatly enhances security, as it mitigates risks associated with compromised passwords, which can occur through phishing attacks or data breaches.

While the other options may touch upon aspects of user experience or convenience, they do not capture the primary purpose and strength of MFA in bolstering security measures effectively.
