How to only allow one admin user to write Firebase Database? : <p>I am trying to set up a Firebase database that only I can write. So no user will have permission to write anything. But everyone will be able to read it.</p>

<p>However, I could not set up the rules for it. I have one admin user that I created using Email/Password login, and I know its UID. Let's say my UID is: <code>dJrGShfgfd2</code></p>

<p>I tried these two methods, but they didn't allow me to write to database.</p>

<pre><code>{
  "rules": {
    "events": {
      ".read": true,
      ".write": "auth.uid === 'dJrGShfgfd2'"
    }
  }
}
</code></pre>

<p>.</p>

<pre><code>{
  "rules": {
    "users": {
      "$user_id": {
        ".read" : true,
        ".write": "$user_id === 'dJrGShfgfd2'"
      }
    }
  }
}
</code></pre>

<p>So how do I allow only one user with a specific UID to write anything to database?</p>
