Two-Factor Authentication (2FA) enhances security by requiring two different types of identification before granting access to an account or system. These identification methods fall into three categories:
- Something only you know: a password or a PIN.
- Something only you have access to: a device such as a smartphone, hardware token, or authentication app.
- Something that is a part of you: biometrics like fingerprints or facial recognition.
By combining two of these methods, 2FA ensures that even if one method (e.g. your password) is compromised, an attacker still needs a second form of authentication to access your account.
