Project Overview

This Password Generator is a versatile Python desktop application that creates secure, customizable passwords. Built with Tkinter, it offers a user-friendly interface that allows for extensive customization of password parameters, provides strength assessment, and includes convenient features like clipboard integration and password saving with expiration reminders.

Interactive Demo

Try out the Password Generator below. Customize your settings and generate a secure password.

Your generated password will appear here
Includes both uppercase and lowercase letters (a-z, A-Z)
Includes numbers (0-9)
Includes symbols like !@#$%^&*()

Minimum Character Counts

Password Strength: Not Generated

Password Security Tips

  • Use a password with at least 12 characters
  • Include a mix of letters, numbers, and special characters
  • Avoid common words and phrases
  • Use different passwords for different accounts
  • Change your passwords regularly
Action completed successfully

Features

Customizable Generation

Adjust password length and choose which character types to include for tailored security needs.

Strength Assessment

Visual strength indicator helps ensure your password meets modern security standards.

Clipboard Integration

Copy passwords to clipboard with one click for easy use in applications and websites.

Password Storage

Save generated passwords to a file for future reference with automatic expiration dates.

Expiration Reminders

Includes expiration dates when saving passwords to encourage regular updates.

Cryptographically Secure

Uses Python's secure random generation for maximum unpredictability and security.

Technical Implementation

The Password Generator is built with Python and leverages several key libraries:

Core Password Generation Logic

def generate_password(length, use_letters, use_digits, use_punctuation, min_letters, min_digits, min_punctuation): if length < (min_letters + min_digits + min_punctuation): return "Password length should be at least the sum of minimum counts for each character type." characters = '' if use_letters: characters += string.ascii_letters if use_digits: characters += string.digits if use_punctuation: characters += string.punctuation if not characters: return "No character types selected." password = [] if use_letters and min_letters > 0: password += [secrets.choice(string.ascii_letters) for _ in range(min_letters)] if use_digits and min_digits > 0: password += [secrets.choice(string.digits) for _ in range(min_digits)] if use_punctuation and min_punctuation > 0: password += [secrets.choice(string.punctuation) for _ in range(min_punctuation)] password += [secrets.choice(characters) for _ in range(length - len(password))] secrets.SystemRandom().shuffle(password) return ''.join(password)

Password Strength Calculation

def calculate_strength(password): length = len(password) has_upper = any(c.isupper() for c in password) has_lower = any(c.islower() for c in password) has_digits = any(c.isdigit() for c in password) has_punctuation = any(c in "!@#$%^&*()-_=+[]{}|;:'\",.<>?/~`" for c in password) strength = 0 if length >= 12: strength += 5 elif length >= 8: strength += 4 elif length >= 5: strength += 2 else: strength += 1 if has_upper: strength += 2 if has_lower: strength += 2 if has_digits: strength += 2 if has_punctuation: strength += 2 return strength

How to Use

  1. Set the desired password length using the slider
  2. Select which character types to include (letters, digits, special characters)
  3. Specify minimum counts for each character type
  4. Click "Generate Password" to create a new password
  5. Use "Copy to Clipboard" to copy the password for immediate use
  6. Optionally use "Save Password" to store the password with an expiration date
  7. Check the strength indicator to ensure your password meets security standards
