Implement Authentication

[khushiagl]

Description:
This issue involves implementing a secure authentication system for the Next.js application using JWT (JSON Web Tokens) for session-based authentication. The goal is to enable secure user authentication, authorization, and session management.

Tasks:

1. Choose an Authentication Strategy

• Use NextAuth.js (recommended) or another authentication library for seamless integration.
• Implement JWT-based authentication for password-based login.

2. Set Up NextAuth.js (or Custom Auth Logic)

• Install and configure NextAuth.js in Next.js.
• Implement JWT token storage and session management.

3. Secure API Routes

• Restrict access to protected API routes by verifying JWT tokens.
• Implement middleware to authenticate and authorize users before allowing access.

4. Configure Environment Variables

• Store OAuth client IDs, secrets, and JWT secret keys securely in .env.local or Vercel environment settings.

5. Implement Login & Logout Functionality

• Create a login page where users can # with email/password or OAuth.
• Provide a logout option to clear authentication tokens and sessions.

6. Implement Role-Based Access Control (RBAC)

• Define user roles (admin, doctor, nurse, etc.).
• Restrict access to certain pages/features based on roles.

7. Test Authentication System

• Verify that users can # with JWT-based credentials and OAuth providers.
• Ensure protected routes are accessible only to authenticated users.

Outcome:

A fully functional authentication system using JWT, allowing users to securely log in, manage sessions, and access protected routes.
