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 ...
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]
The development of open standards such as FIDO2 and WebAuthn have further generated adoption of passwordless technologies such as Windows Hello. On June 24, 2020, Apple Safari announced that Face ID or Touch ID would be available as a WebAuthn platform authenticator for passwordless login.
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.

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 .
WebAuthn is another two-factor mechanism that may be enabled; it is currently not recommended as there is no recovery mechanism for lost keys and it has less support from community volunteers. If you use WebAuthn and have a technical issue, you may lose access to your account forever.
