What is multi-factor authentication?

Multi-factor authentication (MFA) is a security method that requires users to verify their identity in more than one way before they can access an account, application, or system. It adds another layer of security for organizations beyond the traditional username and password.

How does MFA work?

MFA asks users for two or more forms of verification, such as a password plus a code, security key, or biometric check, like a fingerprint or facial recognition.

Why is MFA important?

Attackers can discover user names and steal passwords. MFA adds another layer of protection for an organization’s valuable resources. MFA is designed to make it much harder for attackers to gain access even if they have user credentials.
