title: Firebase how to authenticate user through native facebook app
body: <p>The firebase authentication api uses a browser pop up (Firebase.authWithOAuthPopup() in the new api <a href="https://github.com/firebase/firebase-login-demo-phonegap">cordova example</a> ) . However, on mobile phones, most people use the native facebook app instead. for For cordova phone apps, authenticating through the fb native app has the advantage of not requiring the user to re-enter facebook username and password.</p>
  
  <p>How can fb native app authentication be achieved with the firebase api? </p>
  
  <p>If firebase does not inherently support fb native app authentication, is it possible to use firebase in conjunction with the <a href="https://github.com/Wizcorp/phonegap-facebook-plugin">cordova facebook plugin</a>, which does appear to support native fb app auth. How could this be done?</p>
