title: Where can I get "serviceAccountCredentials.json" for Firebase Admin?
body: <p><a href="https://firebase.google.com/docs/database/admin/start#authenticate-with-admin-privileges" rel="noreferrer">Here</a> is said what I need to setup Firebase on java:</p>
  
  <pre><code>FirebaseOptions options = new FirebaseOptions.Builder()
      .setDatabaseUrl("https://databaseName.firebaseio.com")
      .setServiceAccount(new FileInputStream("path/to/serviceAccountCredentials.json"))
      .build();
  FirebaseApp.initializeApp(options);
  </code></pre>
  
  <p>But where can I get <strong>serviceAccountCredentials.json</strong> ?</p>
  
  <p><strong>UPDATED:</strong>

    "private_key": "",
