Supabase aims to be an open source rival to Firebase. This is crucial for developers who prefer to use open technology in their projects. Other than authentication, it also allows you to build databases and storage buckets. In other words, if your app wants database functionality and stores media files, then Supabase is a great choice in your arsenal.

In this article, you will learn how to build a login system using Supabase’s authentication API. It will also have its own dashboard page. This will be the outcome:
