increases security by verifying identity based on more than just a password or PIN

The two-factor authentication (2FA) increases security by verifying identity based on more than just a password or PIN.

Explanation:

Multi-factor authentication (MFA; encompassing authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something only the user knows), possession (something only the user has), and inherence (something only the user is). MFA protects user data—which may include personal identification or financial assets—from being accessed by an unauthorised third party that may have been able to discover, for example, a single password.

Multi-factor authentication is a process of using a known key and a randomly generated unknown key together to secure an account. This additional security process ensures your account stays safe and reduces the chance of your data getting compromised.
