  • Good quality, secure and maintainable code
  • Easy to use for the end-user

composer require madwizard/webauthn

Usage

The library is still in development so documentation is limited. The general pattern to follow is:

  1. Implement CredentialStoreInterface (you will need UserCredential or your own implementation of UserCredentialInterface)
  2. Create an instance of RelyingParty and use the ServerBuilder class to build a server object:
$server = (new ServerBuilder())
    ->setRelyingParty($rp)
    ->setCredentialStore($store)
    ->build();
  1. Use startRegistration/finishRegistration to register credentials. Be sure to store the temporary AttestationContext server side!
  2. and startAuthentication/finishAuthentication to authenticate. Be sure to store the temporary AssertionContext server side!
