PyGen

A lightweight Password & Email Generator desktop application built with pure Python and Tkinter.

Designed as an educational project to learn about GUI development, modular code organization, and practical utility building in Python.

Features

• Generate randomized or custom emails & secure passwords
• Select character types (lower, upper, digits, symbols)
• Set your name and the domain you want and that's all
• Analyze password strength
• Copy desired results directly to you clipboard
• Save them in separate files

Password Generator

• Generate secure random passwords with customizable length (8–64 characters)
• Select character types: lowercase, uppercase, digits, symbols
• Option to avoid ambiguous characters (l, 1, I, 0, O)
• Real-time password strength analysis with score and verdict
• Copy to clipboard and save to file

Email Generator

• Random mode — generates fully random alphanumeric usernames
• Name-based mode — creates realistic usernames from name pools or custom input
• Choose from preset domains or enter a custom domain
• Email analysis report (username breakdown, format detection, etc.)
• Copy to clipboard and save to file
