title: How to programmatically get the list of registered users in Firebase
body: <p>I am working on an android app based on <a href="https://firebase.google.com/" rel="noreferrer">Firebase</a> and I am creating registration using authentication of users with their email addresses and passwords with method <code>signInWithEmailAndPassword</code>, I am able register multiple users and also able to see user on Firebase console. But, I want to get the list of all the registered users on Firebase Auth. I can get the current user using <code>FirebaseAuth.getInstance().getCurrentUser()</code>. But, I want to list all the registered users. So, is there anyway I can get the list of registered users?</p>
