📌 Overview

Managing passwords can be tedious and unsafe if not done properly. This Password Manager solves that problem by:

• Generating strong and random passwords
• Storing credentials in a local, structured JSON file
• Providing quick search functionality for saved data
• Ensuring ease-of-use through a graphical user interface

This is an ideal project for Python learners, desktop app developers, or anyone looking for an offline personal password vault.

🧠 Key Features

🔑 Password Generation

• Automatically creates strong, unpredictable passwords.
• Includes a mix of uppercase and lowercase letters, numbers, and symbols.
• Passwords are:
  • 8–10 letters
  • 2–4 symbols
  • 2–4 digits
• Generated passwords are automatically copied to the clipboard using pyperclip.

💾 Credential Storage

• User credentials (website, email, password) are stored in a data.json file.
• Uses structured JSON format to support easy updates and lookups.
• Automatically handles:
  • File creation if it doesn’t exist.
  • Merging of new credentials with existing data.
• Validates inputs to prevent empty fields.

🔍 Credential Search

• Enter the name of a website and click Search.
• If credentials exist, a message box displays the stored email/username and password.
• Handles errors like:
  • Missing data.json file
  • Website not found in stored records

📋 Clipboard Copy

• Generated passwords are instantly copied to your clipboard to simplify pasting into websites.

🖥️ Graphical User Interface

💡 How It Works

🧪 Password Generator Logic

password_letters = [choice(letters) for _ in range(randint(8, 10))]

password_symbols = [choice(symbols) for _ in range(randint(2, 4))]

password_numbers = [choice(numbers) for _ in range(randint(2, 4))]

All characters are combined and shuffled.

Final password is inserted into the password entry field.

Password is copied to clipboard automatically.

💽 Save Credentials

When the user clicks Add, credentials are stored in data.json:

{ "example.com": { "email": "user@example.com", "password": "S@f3P@ssw0rd!" } }

If the file does not exist or is empty, it creates a new one.

If it exists, the file is updated with the new entry.

🔍 Find Password

When the user enters a website name and clicks Search, the app:

Looks into data.json

Displays the stored email and password

Error messages are shown for:

Missing file

Website not found
