FIDO security keys are hardware-based security keys that support the FIDO specification to ensure the security of web service accounts.
2What's the difference between FIDO UAF, U2F and FIDO2?
For an overall tutorial of U2F and UAF, please see the below document from FIDO: U2F & UAF Tutorial.
FIDO 2 is comprised of the W3C Web Authentication specification and corresponding Client-to-Authenticator Protocols (CTAP) from the FIDO Alliance. FIDO2 supports passwordless, second-factor and multi-factor user experiences with embedded (or bound) authenticators (such as biometrics or PINs) or external (or roaming) authenticators (such as FIDO Security Keys, mobile devices, wearables, etc.).
3Why should I use FIDO security key?
Traditional password authentication schemes have several security and usability issues. Using simple passwords for multiple sites poses security risks, such as phishing and MITM attacks. Using complex passwords also poses usability issues and frequent password resets. FIDO Security Key provides a secure authentication solution for online accounts using public-key encryption. The Security Key will create a new set of key pairs to increase security.
