title: Firebase blocks all requests after registering 100 users
body: <p>I need to register many generated users in Firebase from web application. I didn't find any methods in API Reference of Firebase to do it in one request, so I call createUserWithEmailAndPassword for every generated pair email/password. After registering 100 users, I get the auth/too-many-requests error and can't send requests for 30 minutes or more because of Firebase blocking all requests from device. </p>
  
  <p>How to prevent blocking my application in firebase console or what to write in code of web application for that? I'm using standart firebase connection:</p>
  
  <pre><code>const config = {
  apiKey: 'my-api-key',
  authDomain: 'my-project.firebaseapp.com',
  databaseURL: 'https://my-project.firebaseio.com',
  storageBucket: 'my-project.appspot.com',
  messagingSenderId: 'my-sender-id'};
  firebase.initializeApp(config);
  </code></pre>
  
  <p>And register every of 100 user with createUserWithEmailAndPassword:</p>
  
  <pre><code>firebase.auth().createUserWithEmailAndPassword(email, password)
  </code></pre>
  
  <p>I'm calling all requests with using Promise.all</p>
  
  <pre><code>firebase.Promise.all(registerRequests)
  </code></pre>
  
  <p>where register request is createUserWithEmailAndPassword promise</p>
