From Get docs

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


The AuthenticatorResponse interface of the Web Authentication API is the base interface for interfaces that provide a cryptographic root of trust for a key pair. The child interfaces include information from the browser such as the challenge origin and either may be returned from PublicKeyCredential.response.

    var assertionResponse = credentialInfoAssertion.response;
    // send assertion response back to the server
    // to proceed with the control of the credential
}).catch(function (err) {
     console.error(err);

    {
      type: "public-key",
