Auth V5 - Next.js Authentication Toolkit

Overview

A complete, production-ready authentication solution built with Next.js 14, Auth.js v5 (NextAuth), Prisma, and PostgreSQL. This project demonstrates modern authentication patterns with a beautiful UI powered by shadcn/ui and Tailwind CSS.

Key Features

• Credentials Login: Email & password authentication with secure bcrypt hashing
• OAuth Providers: Google and GitHub social login integration
• Two-Factor Authentication: TOTP-based 2FA for enhanced security
• Email Verification: Verify user emails before allowing access
• Password Reset: Secure forgot password flow with email tokens
• Role-Based Access Control: Admin and User roles with protected routes
• JWT Sessions: Secure, stateless session management
• CSRF Protection: Built-in protection against cross-site request forgery
• Settings Dashboard: Update profile, change password, enable 2FA

Why I Built This

I wanted to create a comprehensive authentication template that:

• Demonstrates Auth.js v5 best practices and patterns
• Provides a reusable foundation for future projects
• Implements enterprise-grade security features
• Showcases modern Next.js 14 App Router patterns
• Serves as a learning resource for authentication concepts

Tech Stack

• Next.js 14
• TypeScript
• React
• Tailwind CSS
• Shadcn UI
• PostgreSQL & Prisma ORM
• Auth.js v5 (NextAuth)
• Resend (Email Service)
• Zod + React Hook Form
• Vercel (Deployment)

Technical Highlights

• Built secure JWT session strategy reducing database queries while maintaining security
• Implemented seamless OAuth integration with automatic account linking
• Set up TOTP-based 2FA with email backup codes
• Created middleware-based route protection with role-based access
• Used Server Actions for secure auth operations
• Deployed on Vercel with optimized performance

Problem Solved

Implementing authentication correctly is one of the most challenging aspects of web development. Most tutorials oversimplify security, leading to vulnerable applications. This project provides a production-ready template with proper security measures including password hashing, CSRF protection, secure sessions, and multi-factor authentication - all following Auth.js v5 best practices.

What Makes It Unique

Unlike basic auth tutorials, this project implements enterprise-grade features like two-factor authentication, email verification flows, and role-based access control. The combination of Auth.js v5 with Server Actions creates a modern, secure architecture. The beautiful shadcn/ui interface with dark/light mode makes it both functional and visually appealing.

Impact

• Personal Growth: Mastered Auth.js v5 architecture, secure authentication patterns, and Next.js 14 Server Actions - skills essential for any production application
• Real-World Application: Created a reusable authentication template that can be adapted for any Next.js project requiring secure user management
• Portfolio Value: Demonstrates deep understanding of security concepts, OAuth integration, and modern full-stack development practices

Future Plans

• Add magic link authentication
• Implement passkey/WebAuthn support
• Add session management dashboard
• Create account deletion flow
• Add audit logging for security events
