What is the purpose of multi-factor authentication in securing applications?

The purpose of multi-factor authentication (MFA) in securing applications primarily focuses on restricting access to authorized users. MFA enhances security by requiring users to provide two or more verification factors to gain access to an application or system, which reduces the likelihood of unauthorized access.

By implementing MFA, organizations can effectively reduce the risk of credential theft, as an attacker would not only need to obtain a user's password but also the second factor, which could be something they have (like a mobile device) or something they are (like biometric data). This layered approach ensures that only individuals with the legitimate rights to access the application can gain entry, thereby safeguarding sensitive data and systems against unauthorized users and potential breaches.
