What are Free Multi-Factor Authentication (MFA) Apps?

Multi-factor authentication (MFA) software is a security system which requires users to authenticate themselves through multiple credentials. This usually means providing something you know, like a password or PIN, and something you possess, such as a hardware token or biometric data. With this two-factor authentication process, user access can be more securely managed than with traditional single-factor authentication systems.
