title: This app is not authorized to use Firebase Authentication.Please verify that the correct package name and SHA-1 are configured in Firebase Console
body: <p>I'm getting this error when I try to run my app on my android phone:</p>
  <pre><code>This app is not authorized to use Firebase Authentication.
  Please verify that the correct package name and SHA-1 are configured in Firebase Console
  </code></pre>
  <p>I have added both <code>SHA-1</code> and <code>SHA-256</code> code to Firebase console and the package name matches.</p>
  <p>I tried every solution which is available on StackOverflow. I have spent two days to solve this problem but unfortunately, I can't.</p>
