Overview

Integrating authentication into your Next.js 14 application using Supabase can significantly enhance security and user experience. This guide walks through the essential steps to implement email and password authentication, as well as OAuth for Google and GitHub, allowing users to sign in seamlessly and securely. With a focus on protected routes and session management, you’ll be equipped to ensure only authorized access to your application.

In addition to setting up a basic authentication flow, the process involves creating user interfaces for registration and login, handling session management in your application, and ensuring that your app is prepared for real-world scenarios like session expiration. By leveraging Supabase’s powerful backend capabilities alongside Next.js’s features, developers can create robust applications efficiently.
