Multi-factor authentication

Multi-factor authentication is an electronic authentication method that allows a user to use a website or an application by using a combination of multiple factors.

The factors can be classified into three categories: knowing factors (e.g., passwords), having factors (e.g., smartphone app authentication), and equipped factors (e.g.,biometric authentication).

By using multiple elements, even if an ID or password is leaked, other users cannot be successfully authenticated unless other elements are leaked.

Especially, the authentication method that combines two of the above-mentioned factors is called two-factor authentication (2FA).
