Next.js authentication using NextAuth.js is implemented by configuring an auth.ts file to handle OAuth providers, credentials login, and session management. This setup securely authenticates users and manages sign-in and sign-out flows across the application.

Role-based access control in Next.js protected routes is enforced using middleware and server-side checks. This restricts access to specific pages by verifying user roles defined within the JWT or database session strategy.

Auth.js v5 can be used for session management with JWT to persist user authentication state. It supports both JWT and database strategies to securely maintain sessions across your Next.js application.

The best way to add OAuth and credentials login to a Next.js app is using NextAuth.js. It provides seamless integration for providers like GitHub and Google alongside traditional email and password authentication.

You need middleware to secure application routes in Next.js and restrict unauthorized access. Middleware intercepts requests to verify sessions, enabling robust route protection and role-based access control.
