# 🔐 Secure Password Manager (CLI + GUI)

This is a simple and secure Password Manager built with Python. It includes both a **Tkinter-based GUI (Graphical User Interface)** and a **CLI (Command Line Interface)** version.

---

## 📌 Features

* ✅ Generate strong, random passwords
* ✅ Choose what characters to include (lowercase, uppercase, digits, special characters)
* ✅ Real-time password strength feedback
* ✅ Save passwords with labels (e.g., Gmail, Netflix)
* ✅ Encode/Encrypt passwords for security
* ✅ View saved passwords with automatic decryption
* ✅ GUI built using Python's `tkinter` library
* ✅ CLI version with command-line options using `argparse`

## 💡 How It Works

### Tkinter GUI

The graphical interface is built using `tkinter`, Python’s standard GUI toolkit. It provides a clean interface for generating, encrypting, and viewing passwords.

### Generate Password

1. Choose the password length.
2. Select character types using checkboxes.
3. Hit the **Generate Password** button.
4. The password is displayed with its strength (Weak, Medium, or Strong).
5. The password is then **encrypted** and saved to a file.

### View Saved Passwords

1. Click the **View Saved Passwords** button in the GUI.
2. If the encryption key exists, the program decrypts and displays all saved passwords in a pop-up window.
3. If the key is missing or corrupted, an error message is shown.

## ⚠️ Security Note

This project uses **Fernet encryption** to protect your saved passwords.

Files like `secret.key` and `saved_passwords.txt` are excluded from version control using `.gitignore`.

> Do not share your `secret.key` with anyone. If you lose it, saved passwords cannot be decrypted.
