WebAuthn Emulator
=================

[](#webauthn-emulator)

*A simple PHP WebAuthn (FIDO2) client library*

`webauthn-emulator` is a PHP library that emulates WebAuthn-compatible authenticators like YubiKeys, Touch ID, Face ID, Windows Hello, etc. It essentially simulates the behavior of [Web Authentication API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API) of a browser, allowing the developers to integrate WebAuthn client-side authentication into their applications.
