flask-login-project

Flask login system (under development)

🔐 Flask Authentication System (ADS Project)

This is a complete full-stack authentication system, developed as a practical project for the Systems Analysis and Development (ADS) degree program. The project implements the fundamental concepts of web development, relational database persistence, and session management.

🚀 Overview

The application provides a solid foundation for user management, featuring a modern Dark Mode interface. The project demonstrates the integration of a Python backend with a database to handle user registration, secure login, and route protection logic.

🛠️ Technologies Used

• Backend: Python with Flask (Micro-Framework)
• Database: SQLite3 (Relational Data Management)
• Frontend: HTML5 and CSS3 (Custom Interface)
• Sessions: Flask-Session for secure user state persistence.

✨ Main Features

• User Registration: Real-time validation to prevent duplicate usernames using SQL UNIQUE constraints.
• Secure Login: Credential verification directly against the SQLite database.
• Protected Dashboard: Routes accessible only to authenticated users through session verification.
• Flash Messages: Dynamic visual alerts for successful or failed actions (e.g., "Access Denied", "Welcome").
• Data Persistence: Information is stored in a local .db file, ensuring that data is not lost when the server restarts.
