🔐 Internet Authentication Page

A simple authentication page for controlling network access, built using HTML, CSS, and JavaScript with a Python Flask backend. This project is a simple sets up an authentication page for internet access within a local network. The authentication page is hosted using a Python-based web server and automatically starts on system boot

🚀 Features

✔️ User authentication page hosted on a specific IP.
✔️ Python Flask server to handle login requests.
✔️ Automatically starts on system boot via start_auth_server.bat.
✔️ Securely restricts access based on network configurations.

🔧 Installation & Setup

1️⃣ Install Dependencies

Ensure Python is installed, then run:

pip install flask

2️⃣ Run the Authentication Server

python auth_server.py

The server will be accessible on your configured IP.

3️⃣ Auto-Start on Boot (Windows)

Place start_auth_server.bat in shell:startup to launch the server at system boot.

⚠️ Important

Ensure that the correct path to auth_server.py is set in the start_auth_server.bat file. Update the .bat file with the absolute path to auth_server.py, like this:

@echo off
cd /d "C:\Path\To\Your\Project\Folder"
python auth_server.py

Replace "C:\Path\To\Your\Project\Folder" with the actual directory where your auth_server.py is located.

🌐 Hosting on a Specific IP

Modify auth_server.py to bind the server to a particular IP:

app.run(host='192.168.1.1', port=5000)

Ensure the firewall allows access to the selected IP.

🔐 Authentication Details

To log in to the authentication page, use the following credentials:

Username: admin  
Password: pass123  

Ensure these credentials are correctly configured in your auth_server.py or database if modified.

⚠️ Disadvantage

Currently, when the server starts using start_auth_server.bat, it prompts for admin approval (UAC prompt). This can be inconvenient as it requires manual confirmation each time the system boots.

🔧 Future Improvement: In upcoming sessions, we will work on a method to bypass the admin prompt securely while maintaining system integrity.

Future Enhancements

🚀 Database Integration – Store login credentials securely.
🔑 Multi-Factor Authentication (MFA) – Enhance security.
📊 Admin Panel – Monitor and manage connected users.
🔗 Custom Captive Portal – Redirect unauthenticated users automatically.
