🔐 Secure Password Manager

A simple and secure Password Manager built using Python. It provides a graphical interface to securely store, manage, generate, and retrieve passwords.

📌 Features

• 🔑 Master password protection
• 🔒 AES-256-GCM encryption for stored passwords
• 🗄️ SQLite database for storing password information
• 🎲 Secure password generator
• 💪 Password strength checker
• 🚨 Password breach checking
• 🔍 Search saved passwords
• 👁️ Show/Hide password option
• 📋 Copy password to clipboard
• ⏱️ Automatic session lock
• 📤 Export password data to JSON
• 🗑️ Add, retrieve, update, and delete passwords

🛠️ Technologies Used

• Python
• Tkinter – Graphical User Interface
• SQLite3 – Database
• Cryptography – Password encryption
• AES-256-GCM – Encryption method
• PBKDF2-HMAC-SHA256 – Key derivation
• Base64 – Secure data encoding

⚙️ Requirements

Make sure Python is installed on your computer.

Install the required library:

pip install cryptography

Tkinter and SQLite3 are included with most Python installations.

▶️ How to Run

1. Clone the repository:

https://github.com/bhavyweb3/Secure-Password-Manager.git

2. Open the project folder:

cd YOUR-REPOSITORY

3. Install the required package:

pip install cryptography

4. Run the application:

python main.py

🔐 How It Works

The application uses a master password to protect access to stored passwords.

Passwords are encrypted before being stored in the SQLite database. The project uses AES-256-GCM encryption and PBKDF2-HMAC-SHA256 for secure key generation.

The application also provides a secure password generator and checks password strength.

🗄️ Database

The application uses a local SQLite database:

passwords_secure.db

The database stores information such as:

• Service name
• Username
• Encrypted password
• Salt
• Initialization Vector (IV)
• Authentication tag
• Created and updated time

Passwords are not stored as plain text.

🔑 Security Features

• AES-256-GCM encryption
• Secure random password generation
• Strong master password validation
• PBKDF2 key derivation
• Automatic session timeout
• Clipboard auto-clear
• Password strength analysis

🚨 Breach Monitoring

The project includes a password breach checking feature. The current implementation uses a built-in list and simulated breach checking for demonstration purposes.
