How does multi-factor authentication (MFA) enhance cloud security?

Multi-factor authentication (MFA) significantly enhances cloud security by requiring users to verify their identity using more than one method of authentication. This layered approach adds an extra barrier against unauthorized access. In practice, MFA typically involves the combination of something the user knows (like a password), something the user has (such as a mobile device or security token), or something the user is (biometric factors like fingerprints or facial recognition).

The rationale behind using multiple factors is that if one method is compromised—for example, if a password is stolen—an attacker would still need the additional verification method (such as a code sent to the user’s phone or a biometric check) to gain access. This significantly reduces the likelihood of unauthorized access, as it is much harder for attackers to acquire multiple forms of authentication simultaneously.

The other options do not correctly reflect how MFA enhances security. While simplifying passwords and increasing data storage limits may improve user experience and efficiency in some contexts, they do not directly contribute to the security enhancements that MFA offers. Eliminating the need for user access management is also incorrect, as effective management of access rights remains a critical component of any robust security strategy, regardless of whether MFA is implemented.
