Passkey validator

Other components that this module uses or need:

• Web -> WebAuthnValidation To authenticate users using a Passkey you need to have a database connection. https://docs.fortifiedid.se/tokens/

• Enrollment -> Check out the Enrollment documentation. To be able to authenticate you must have enrolled for a token.

Configuration

Authenticator type: Passkey

Common Authenticator configuration can be found here.

Properties

Name	Description	Default value	Mandatory
namespace
username_parameter		username

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.

Logging

• WEB_100022("Passkey validated")

  • IDENTIFIER (user trace id)

  • CUSTOMER_IDENTIFIER (if configured)

  • SOURCE_ADDRESS (ip of the remote session)

• WEB_100023("Passkey validation failed")

  • IDENTIFIER (user trace id)

  • CUSTOMER_IDENTIFIER (if configured)

Global state

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"
}
