How to secure a Firebase database if I don't want users to have a login? : <p>I want to store some user information without any authentication from Android. The information is not important, doesn't need to be secure and the users don't need to have a login. The only way I've figured out how to do it is to use these rules:</p>

<pre><code>{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}
</code></pre>

<p>But firebase tells me that is not secure and I should secure it. So how can I secure it? I am using <code>signInAnonymously()</code> on the <code>FirebaseAuth</code> instance. </p>
