title: Firebase Rules for Realtime Database Without Using Firebase Authentication
body: <p>I'm pretty new with Firebase Service, but I've already completed code for my iOS app which is responsible for Firebase Realtime Database Interaction.</p>
  
  <p>Now I want to make my app secured and protect it with Firebase Rules. There is a problem that I'm using my own authentication for users and therefore I don't use Firebase Auth.</p>
  
  <p>So the question is how can I secure my database using Firebase Rules and without Firebase Auth.</p>
