How to enable FIDO2 authentication

FIDO2 is an authentication standard hosted by FIDO Alliance. 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. The WebAuthn API is backward compatible with Universal 2nd Factor (U2F) keys.

Centrify leverages the WebAuthn API to enable passwordless authentication to the Privileged Access Service using either on-device or external authenticators. On-device authenticators are biometric authenticators integrated into the device hardware. Popular examples are Mac Touch ID, Windows Hello, and fingerprint scanners. External authenticators are security keys that you plug into the device's USB port; for example, a YubiKey.
