title: Do I have to change security rules in firebase if I'm not using database?
body: <p>If I were to build a site without database interaction (no login on the site) with firebase. Do I need to change default security rules that looks like this:</p>
  
  <pre><code> {
          "rules": {
              ".read": true,
              ".write": true
          }
  
   }
  </code></pre>
  
  <p>This red exclamation sign in the security &amp; rules section says that I better write some security rules. So the question is, is it safe to leave this as is if you don't use login/signup ?</p>
