Refer to and for more information about WebAuthn and FIDO2, respectively.

Refer to NIST 800-63b for more information about multi-factor cryptographic devices. Popular examples are biometric authenticators integrated into device hardware, such as Mac Touch ID, Windows Hello, and fingerprint scanners. Supported multi-factor FIDO2 authenticators are something you are. Refer to NIST 800-63b for more information about single-factor cryptographic devices. Examples are external authenticators like security keys that you plug into the device's USB port for example, a YubiKey. Single-factor FIDO2 authenticators are something you have. The WebAuthn API is backward compatible with Universal 2nd Factor (U2F) keys.ĬyberArk leverages the WebAuthn API to enable passwordless authentication to the CyberArk Identity using either external or on-device authenticators. This standard includes the Web Authentication ('WebAuthn') API, which is a specification written by the World Wide Web Consortium (W3C) and FIDO, with participation from additional third parties.

FIDO2 is an authentication standard hosted by FIDO Alliance.
