Example

{
  "id": "passkey",
  "type": "Passkey",
  "config": {
    "namespace": "default",
    "base_path": "/saml/authn",
    "context_path": "/saml/authn/webauthn",
    "webroot_dir": "web/authenticator/webauthn",
    "username_parameter": "username"
  }
}

Property base_path should not contain the full path when used in conjunction with the Selector, instead, the full URI will be handled by the selector. The full path will be base_path + / + id.

Global state

After successful authentiation, the authenticator populates the configured username property with the user identifier obtained during the Web Authentication process.

API

The following documentation contains links to the document Web Authentication: An API for accessing Public Key Credentials Level 2, W3C Recommendation, 8 April 2021.

Begin authentication

Initialize a new authentication with the following request to the authenticator API:

{
    "type": "options"
}

The server responds with a PublicKeyCredentialRequestOptions. Use the response to obtain a AuthenticatorAssertionResponse, according to the Web Authentication specification, and return the assertion to the authenticator API:

{
    "type": "verification",
    "data": {
        "assertion": <AuthenticatorAssertionResponse>
    }
}

The server responds with AUTHORIZED or UNAUTHORIZED:

{
    "status": "AUTHORIZED|UNAUTHORIZED"
}
