Web Authentication (WebAuthn) is a web standard published by the World Wide Web Consortium (W3C). [1] [2] [3] WebAuthn is a core component of the FIDO2 Project under the guidance of the FIDO Alliance. [4] The goal of the project is to standardize an interface for authenticating users to web-based applications and services using public-key ...
A web user agent (i.e., a web browser) together with a WebAuthn client form an intermediary between the authenticator and the relying party. A single WebAuthn client Device may support multiple WebAuthn clients. For example, a laptop may support multiple clients, one for each conforming user agent running on the laptop.
An authenticator that implements CTAP2 is called a FIDO2 authenticator (also called a WebAuthn authenticator). If that authenticator implements CTAP1/U2F as well, it is backward compatible with U2F. The protocol uses the CBOR binary data serialization format. The standard was adopted as ITU-T Recommendation X.1278. [6] [1]
WebAuthn and CTAP provide a complete replacement for U2F, which has been renamed "CTAP1" in the latest version of the FIDO2 standard. [37] The WebAuthn protocol is backward-compatible (via the AppID extension) with U2F-only security keys [38] but the U2F protocol is not compatible with a WebAuthn-only authenticator.
For example, a FIDO2 authenticator that implements the CTAP2 protocol [16] is a roaming authenticator that communicates with a WebAuthn client via one or more of the following transport options: USB, near-field communication (NFC), or Bluetooth Low Energy (BLE).
