title: Can I use Firebase Auth without a database?
body: <p>I'm trying to add Authentication to a React Web App (typescript) and I see that &quot;firebase/auth&quot; could be all I need. But this is the configuration:</p>
  <pre><code>var firebaseConfig = {
      apiKey: &quot;xxxxxxxxxxxxxxxxxxxxxxxxxxxx&quot;,
      authDomain: &quot;xxxxxxxxxxxx&quot;,
      databaseURL: &quot;xxxxxxxxxx&quot;,
      projectId: &quot;xxxxxxxxxx&quot;,
      storageBucket: &quot;xxxxxxxxxxx&quot;,
      messagingSenderId: &quot;xxxxxxxxxxxxxxxxxxx&quot;,
      appId: &quot;1:xxxxxxxxx:web:xxxxxxxxxxxxxx&quot;,
      measurementId: &quot;xxxxxxxxx&quot;
    };
  </code></pre>
  <p>Do I need databaseURL? or storageBucket?  My intention is to JUST AUTHENTICATE using Google auth for now and match the user in my database with a google ID or whatever Firebase Auth unique id has. What are the consecuences to skip databaseURL and/or storageBucket when configuring.?</p>
