How Does 2FA Work?
Two-factor authentication (2FA) is a type of multi-factor authentication (MFA). It strengthens user access security by requiring two methods (or two factors) to verify the user’s identity. One of these factors could be something known by the user (like a login name and password), whereas the second one could be something owned by the user (like an authentication app or a smartphone).
Two-factor authentication (2FA) is a great way to protect users against phishing scams, social engineering, and brute-force attacks on passwords. It secures the login process against attacks that exploit weak or stolen credentials.
