    web.console.warn(
        "The `signIn` method is discouraged on the web because it can't reliably provide an `idToken`.\n"

  }

  // This method mainly does oauth2 authorization, which happens to also do
  // authentication if needed. However, the authentication information is not
  // returned anymore.
  //
  // This method will synthesize authentication information from the People API
  // if needed (or use the last identity seen from signInSilently).
