🔐 Password Generator

A Python application for generating secure passwords using Object-Oriented Programming (OOP) and Abstract Base Classes (ABC). This project demonstrates inheritance, abstraction, and polymorphism by implementing multiple password generator classes.

🚀 Installation

Clone the repository:

git clone https://github.com/your-username/PasswordGenerator.git

Navigate to the project folder:

cd PasswordGenerator

No external dependencies are required.

---

▶️ Usage

Run the application:

python main.py

The program generates three different passwords:

• Numeric password
• Letter-only password
• Mixed password (letters and numbers)

---

💻 Example Output

48291
gKdPw
H7sP2

Output will be different each time because the passwords are generated randomly.

Each subclass implements its own version of the generate_password() method.

🔮 Future Improvements

• Add special characters support
• Password strength checker
• Command-line arguments
• Interactive user input
• GUI version using Tkinter or PyQt
• Save generated passwords to a file
