Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) is an essential security feature that requires users to provide two or more verification factors to gain access to a system. This added layer of security significantly reduces the chances of unauthorized access. Common forms of MFA include:
Something you know: A password or PIN.
Something you have: A physical token, such as a smartphone app or hardware key, that generates a time-sensitive one-time passcode.
Something you are: Biometrics such as fingerprints, facial recognition, or retinal scans.
By implementing MFA, even if an attacker manages to steal a user's password, they still cannot access the account without the second or third verification factor.
