What is Multi-Factor Authentication (MFA)?
- Multi-factor authentication (MFA) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more types of evidence (or factors) to an authentication mechanism: knowledge (something only the user knows), ownership (something only the user has), and discovered that the relationship persists (something only the user is).
- Multi-Factor Authentication (MFA) is a security feature that adds an extra layer of security to user-name and password authentication.
- MFA prevents unauthorized third parties who have discovered, for example, a single password from accessing user data, which may include identity information or financial assets.
Therefore, Multi-Factor Authentication (MFA) is a feature that provides an additional layer of security on top of user-name and password authentication.
