Multi-factor authentication (MFA) is a security method that requires users to provide multiple forms of identification to gain access to an account or system.
Typically, this involves a combination of something the user knows (such as a password or PIN), something the user has (such as a mobile device or security token), and something the user is (such as biometric information like a fingerprint or facial recognition).
By requiring multiple factors for authentication, MFA adds an extra layer of security, making it more difficult for unauthorized users to gain access, even if they have obtained a user's password. This helps safeguard sensitive information and protects against unauthorized access to digital systems and accounts.
