PublicKeyCredential: rawId property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.
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.
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
const 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: "[email protected]", displayName: "Carina Anand", }, pubKeyCredParams: [ { type: "public-key", alg: -7, }, ], }; navigator.credentials .create({ publicKey: options }) .then((pubKeyCredential) => { const rawId = pubKeyCredential.rawId; // Do something with rawId }) .catch((err) => { // Deal with any error }); Specifications
