Multi-Factor Authentication (MFA)

A security mechanism that requires users to verify their identity using two or more authentication factors.

Expanded Explanation

Multi-Factor Authentication enhances security by requiring a combination of something you know (password), something you have (security token), and something you are (biometrics). It’s widely used to secure access to email accounts, banking systems, and enterprise platforms, significantly reducing the risk of unauthorized access even if a password is compromised.
