What is the primary purpose of Multi-Factor Authentication (MFA) in identity protection?

The primary purpose of Multi-Factor Authentication (MFA) in identity protection is to enhance security by requiring two or more verification methods. MFA goes beyond just a username and password, which can be easily compromised, by adding additional layers of security. This typically includes something the user knows (like a password), something the user has (like a mobile device or hardware token), and/or something the user is (like biometric data).

By implementing MFA, organizations can significantly reduce the risk of unauthorized access to sensitive systems and data. Even if a user's password is stolen or guessed, the attacker would still need the second (or additional) form of verification to gain access. This additional requirement makes it much more difficult for unauthorized users to breach accounts, thereby strengthening the overall security posture of an organization.

Other options, while relating to identity management, do not directly address the core function of MFA. Storing user credentials securely pertains to password management practices, single sign-on focuses on user convenience with access management, and tracking user access is more about auditing and monitoring rather than authentication processes.
