Web/API/AuthenticatorAttestationResponse

Secure contextThis feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The AuthenticatorAttestationResponse interface of the Web Authentication API is returned by CredentialsContainer.create() when a PublicKeyCredential is passed, and provides a cryptographic root of trust for the new key pair that has been generated. This response should be sent to the relying party's server to complete the creation of the credential.

This interface inherites from AuthenticatorResponse.

Note: This interface is restricted to top-level contexts. Use from within an <iframe> element will not have any effect.

Properties

AuthenticatorAttestationResponse.clientDataJSON Secure contextRead only: Client data for the authentication, such as origin and challenge. The clientDataJSON property is inherited from the AuthenticatorResponse.
AuthenticatorAttestationResponse.attestationObject Secure contextRead only: An ArrayBuffer containing authenticator data and an attestation statement for a newly-created key pair.

Methods

AuthenticatorAttestationResponse.getTransports()Secure context: Returns an Array of strings describing which transport methods (e.g. usb, nfc) are believed to be supported with the authenticator. The array may be empty if the information is not available.

Examples

var publicKey = {
  challenge: /* from the server */,
  rp: {
    name: "Example CORP",
    id  : "login.example.com"
  },
  user: {
    id: new Uint8Array(16),
    name: "[email protected]",
    displayName: "John Doe"
  },
  pubKeyCredParams: [
    {
      type: "public-key",
      alg: -7
    }
  ]
};

navigator.credentials.create({ publicKey })
  .then(function (newCredentialInfo) {
    var response = newCredentialInfo.response;
    // Do something with the response
    // (sending it back to the relying party server maybe?)
  }).catch(function (err) {
     console.error(err);
  });
