Firebase Authentication - trackjs/javascript-gameshow

Firebase Authentication is a service provided by Firebase that allows for user authentication using various methods. It is easy to use and integrates directly with the Firebase Database, making data control and access easier for developers. Firebase Authentication supports several ways to authenticate users, including email & password, Google, Facebook, Twitter, and phone number. It also offers offline capabilities, allowing apps to function even without an internet connection. Additionally, Firebase Authentication can be used with Firebase Dynamic Links.

To set up Firebase Authentication in a project, follow these steps:

  1. Create a new Firebase project or use an existing one.
  2. Choose the type of app and name it.
  3. Select the features you want to include, such as Firebase Authentication and Cloud Firestore Database.
  4. Initialize Firebase Authentication and other features.

Here are some code snippets and documentation that demonstrate how to use Firebase Authentication in a project:

  1. admin.js: This code snippet shows how to use Firebase Authentication to sign in and sign out users using GoogleAuthProvider. It also shows how to update the active question and answers in the Firebase Realtime Database.
document.querySelector("#login-button").addEventListener("click", async (evt) => {
evt.preventDefault();
const provider = new firebase.auth.GoogleAuthProvider();
await firebase.auth().signInWithPopup(provider);
});

document.querySelector("#logout-button").addEventListener("click", async (evt) => {
evt.preventDefault();
await firebase.auth().signOut();
location.reload();
});
