Multi-Factor Authentication (MFA) is a security process that requires users to verify their identity through two or more authentication factors before gaining access to an account or system. These factors typically include:
A common use case for MFA is securing cloud storage and online banking. Even if a hacker steals a user’s password, they still need an additional authentication factor—such as a one-time code sent to a phone or a fingerprint scan—to gain access. MFA significantly enhances security by preventing unauthorized access, especially against phishing and credential theft attacks. Many organizations now require MFA as a standard cybersecurity best practice.
