   * @method open

   * the promise will resolve an object containing the following keys:
   *   - authorizationToken: The `token` from the 3rd-party provider
   *   - provider: The name of the provider (i.e., google-oauth2)
   *   - redirectUri: The redirect uri (some server-side exchange flows require this)
   * If there was an error or the user either canceled the authorization or
   * closed the popup window, the promise rejects.
