Authentication, the ability to create users and sign in to a website, can be tricky to set up. This course is designed to simplify the process and walk you through how to do it step by step.

Learn how to authenticate users with email, Google, Facebook, Twitter, and Github. Users will also be able to reset their passwords or delete their accounts.

After authenticating we will build a "to-do list" application that demonstrates how to store data related to the user. This is commonly referred to as authorization. In this app, the user will be able to save tasks for themselves and also view or mark them as complete.

While learning authentication we also extend the app so you end up getting experience with a lot of the Firebase services. For instance, this course uses Firebase Storage for profile uploading, the Realtime Database for to-do list items and Firebase Hostingfor a fully deployed live site.

Firebase is hands down the fastest way to create full-stack applications in 2019. Firebase is a suite of cloud services backed by Google that allows you to launch applications extremely quickly. Because it's a BaaS (Backend as a Service) you get all the benefits of a backend without the complications of setting one up. Firebase's services are 100% free until you reach a monthly data cap. It's meant to be enough for testing full-stack apps on the platform but it's enough to run your site live for FREE (if your app is in its beginning stages - upgrade if needed). This guide assumes you have some JavaScript knowledge but absolutely zero knowledge of Firebase.
