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 transports = newCredentialInfo.response.getTransports();
    console.table(transports); // may be something like ["internal", "nfc", "usb"]
  }).catch(function (err) {
