Face Recognition Login System with GUI in Python – Free Source Code

Face Recognition Login System with Python GUI – Free Source Code

Are you looking for a secure and modern way to log in using your face? Look no further! In this post, we bring you a free, complete Face Recognition Login System using Python with a user-friendly GUI interface built with Tkinter. Whether you're a beginner or an advanced developer, this open-source project will help you learn how facial authentication works in real life.

This system captures a user’s face, saves it with a unique ID, trains the model, and then allows login using facial recognition. Once authenticated, it displays a personalized welcome screen showing the user's name. All done in Python, and it’s absolutely free to download.

✅ Key Features

• 🔐 Login using face recognition (LBPH algorithm)

• 🧑‍💻 User registration system with name mapping

• 💾 Face training model storage

• 📁 JSON-based user data mapping

• 🎨 Modern GUI using Tkinter (no command line needed)

• ✅ Clean folder structure (dataset, trainer, users)

• 💡 Built-in error handling for JSON and camera issues

  
  

  
  

📁 What's Inside the Source Code?

The zip file includes the following:

• face_login_gui.py – main Python program

• users.json – user ID to name mapping

• dataset/ – stores captured face images

• trainer/ – stores the trained model file

• All supporting assets to run the GUI app locally

🎯 Technologies Used

• Python 3+

• OpenCV (for face detection and recognition)

• Tkinter (for GUI)

• JSON (to store user profiles)

💻 How It Works

1. Register Face – Users enter their name and the app captures 20 images using their webcam.

2. Train Model – The system processes and trains the model based on registered images.

3. Login by Face – When the user looks into the webcam, the system recognizes the face and shows a welcome message with their name.

4. Welcome Page – A personalized greeting after successful authentication.
