PublicKeyCredential.rawId

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

The rawId read-only property of the PublicKeyCredential interface is an ArrayBuffer object containing the identifier of the credentials.

The PublicKeyCredential.id property is a base64url encoded version of this identifier.

Note: This property may only be used in top-level contexts and will not be available in an <iframe> for example.

Syntax

rawId = publicKeyCredential.rawId

Value

A ArrayBuffer containing the identifier of the credentials. This identifier is expected to be globally unique and is appointed for the current PublicKeyCredential and its associated AuthenticatorAssertionResponse.

Examples

var options = {
  challenge: new Uint8Array(26) /* from the server */,
  rp: {
    name: "Example CORP",
    id  : "login.example.com"
  },
  user: {
    id: new Uint8Array(26), /* To be changed for each user */
    name: "jdoe@example.com",
    displayName: "John Doe",
  },
  pubKeyCredParams: [
    {
      type: "public-key",
      alg: -7
    }
  ]
};

navigator.credentials.create({  publickey: options })
  .then(function (pubKeyCredential) {
    var rawId = pubKeyCredential.rawId;
    // Do something with rawId
}).catch(function (err) {
  // Deal with any error
});
