What role does multi-factor authentication serve in security?

Multi-factor authentication (MFA) plays a critical role in enhancing security by requiring users to provide two or more verification factors to gain access to a system or application. This means that even if a password is compromised, an attacker would still need additional authentication—such as a fingerprint, a text message code, or a hardware token—to gain access. The use of multiple factors significantly reduces the likelihood of unauthorized access, making it a robust defense against various cyber threats like phishing or brute force attacks.

By implementing MFA, organizations can strengthen their security posture, ensuring that only legitimate users can access sensitive information or systems, which is especially important in an environment where data breaches are increasingly common.
