Password Manager🔑

Description

This is a Password Manager built with Python and Tkinter, designed to help users securely store and generate passwords locally. The application allows users to enter, save, and search for their website credentials (username and password) with the option to generate strong passwords. The project demonstrates the use of Object-Oriented Programming (OOP), graphical user interfaces (GUI), file handling in Python, and JSON for data storage.

Features

• Password Generation: Generates secure random passwords with a combination of lowercase, uppercase, numbers, and special characters.
• Password Saving: Saves entered passwords to a data.json file, allowing users to retrieve their saved passwords later.
• Password Validation: Ensures that generated passwords meet common security requirements such as length and character variety.
• Password Search: Quickly search for saved credentials by entering the website name in the search bar.
• GUI Interface: Provides an easy-to-use graphical interface for interacting with the password manager.
• JSON Data Storage: Credentials are stored in a structured JSON format for efficient management and retrieval.

Requirements

• Python 3.x
• pyperclip (install via pip install pyperclip)
• tkinter (pre-installed with Python)

How to Use

Click here for detailed instructions

1. Start the Application:

   • Run the main.py script using Python. This will open the password manager GUI.

2. Input:

   • Website: Enter the website for which you're saving credentials.
   • Username: Enter the associated username or email address.
   • Password: Enter the password for the website or generate a new one using the "Generate Password" button.

3. Functionality:

   • Click the "Generate Password" button to generate a new password, which will automatically be copied to your clipboard.

   • After filling in the details, click the "Add" button to save the credentials to data.json.

   • Use the "Search" button to find credentials for a specific website. Enter the website name in the Website field, and a popup will display the corresponding email and password if found.

     

4. Empty Fields Warning:

   • If any of the fields (Website, Username, or Password) are left empty and the "Add" button is clicked, a warning message will appear, asking the user to fill in all fields before saving.

  • generate_password(self): Generates a random password and inserts it into the password entry box.
  • save(self): Saves the entered data (website, username, and password) to data.json.
  • search(self): Searches for a website in the JSON file and displays the associated email and password.
  • password_validation(self): Validates the password to meet security requirements using a regex pattern.

constants.py

• Purpose: Stores constant values like the font name used in the app.

data.json

• Purpose: Stores the saved website credentials (website, username, and password) in a structured JSON format.

logo.png

• Purpose: The image file for the logo that is displayed on the app's GUI.

How to Run

1. Clone or download the project files.
