What is WebAuthn?

WebAuthn (Web Authentication API) is a global standard specification for secure authentication on the Web, formulated in 2018 by the World Wide Web Consortium (W3C).

This browser-based API allows user authentication on web applications through the creation of strong “credentials” and user-agent-mediated access to authenticators. This could be either in the form of hardware tokens (like U2F security keys) or in-built modules (biometric readers like Google Hello, Apple Touch ID) in the platform. Web Authn has garnered the support of all leading browsers like Chrome, Firefox, and Edge, and is compatible with all leading platforms.
