Firebase Authentication

Authenticating users with Firebase Authentication

Our application might need to have access to the user’s identity to save user data securely, give the user access to privileged features, or personalize their experience.

Firebase Authentication provides back-end service SDKs to authenticate users to our app. It supports authentication using phone numbers, passwords, and other identity providers like Google, X (formerly Twitter), and Meta.

In this lesson, we’ll learn how to authenticate our users with Google or an email and password with Firebase Authentication.

To use Firebase Authentication in our app, follow the steps below:

1. Create a project on Firebase Console
2. Enable Firebase Authentication on Firebase Console
3. Add and initialize Firebase in the app
4. Authenticate users
