🔐 Authentication System

A proof-of-concept project focused on designing and implementing an authentication system. The application is built using Next.js and Spring Boot.

⚙️ Tech Stack

• Next.js
• React
• TypeScript
• Java
• Spring Boot

✨ Features (In Progress)

• Email-based authentication with session management
• OAuth authentication flow
• Email verification, 2FA and password recovery

📍 Motivation

In my previous projects, I did not dive deep into auth systems as they would either be handled by third party services like Firebase or they were not a primary focus. So, I wanted to build this project to understand the behind the scenes of an auth system while also learning about how these systems could be compromised and potential vulnerabilities.

▶️ Running the Project

This project consists of a frontend and backend that need to be run separately.

Backend (Spring Boot)

1. Navigate to the backend/auth folder

cd backend/auth

2. Run the Spring Boot Application

./mvnw spring-boot:run

3. The backend server will run on http://localhost:8080

Frontend (Next.js)

1. Navigate to the frontend folder

cd frontend

2. Install dependencies:

npm install

4. Run development server:

npm run dev

6. Open http://localhost:3000 in your browser
