Handling Authentication in Next.js

Authentication is essential for securing user data in Next.js applications. It allows users to verify their identity and access protected resources. Next.js supports various authentication methods, including NextAuth.js, JWT, and Firebase, making it easy to integrate authentication without complex configurations.

Implementing NextAuth.js

import NextAuth from "next-auth";
import Providers from "next-auth/providers";


export default NextAuth({
  providers: [
    Providers.GitHub({
      clientId: process.env.GITHUB_CLIENT_ID,
      clientSecret: process.env.GITHUB_CLIENT_SECRET,
    }),
  ],
});

• Simplifies authentication with built-in providers.
• Secure session handling.
• Reduces boilerplate code.

Conclusion

Using NextAuth.js or JWT makes authentication easier and more secure in Next.js applications, ensuring users can log in safely and access protected routes.
