What is FIDO?

Fast Identity Online (FIDO) is a technical specification for online user identity authentication. It is used in scenarios such as fingerprint login and two-factor login, allowing users to use biological features or a FIDO security key to log in to online accounts. Since it improves security, protects privacy, and simplifies the verification experience, devices such as Windows devices, iPhones, and Huawei phones all support this verification solution.

Two-factor authentication (2FA): It is also called two-step authentication and is a security authentication process. In this authentication process, users are required to provide two different authentication factors to prove their identities, thereby better protecting user certificates and resources accessible to users. For two-factor authentication, users are required to provide a second factor other than their password. Generally, the second factor is a security token or a biometric recognition factor, such as fingerprint and face enrollment.

For example, when transferring money, you need to confirm the transfer on the USB key in addition to providing your password.
