Restrict Firebase database access to one Android app

Question

I\'m working on an Android app that reads from a Firebase database. App users won\'t be logging in or modifying the database. All app users will be looking at the same dat

Answer 1

When you add your application to Firebase project, you must specify SHA1 certificate of your app, so nobody is able to access your data except you.

Answer 2

3. Use FirebaseAuth and signInAnonymously() method

reference: https://firebase.google.com/docs/auth/android/anonymous-auth

Then adjust security rules:

    {
      "rules": {
        ".read": "auth != null",
        ...
      }
    }

Con: multiple accounts used only for reading the same data
