Two-Factor Authentication (2FA)
Two-Factor Authentication (2FA) is a security process that requires users to provide two distinct forms of identification before accessing an account or system. Typically, 2FA combines something the user knows (like a password) with something the user has (such as a physical token or a mobile device) or something the user is (biometric data like fingerprints). Implementing 2FA significantly enhances security by adding an extra layer of protection against unauthorized access, even if passwords are compromised.
