Secure Password Generator
A modern, secure, and customisable password generator with real-time strength analysis, dark mode, and exportable history, built with HTML, Tailwind CSS, and JavaScript.
PassWhiz is a secure, customisable, and AI-enhanced password generator built with HTML, CSS (TailwindCSS), and JavaScript. The application enables users to generate strong, random passwords based on customizable criteria, such as length, character types, and pronounceability. It features a real-time strength indicator, copy-to-clipboard functionality, and password history tracking with CSV export.
The project is designed with a modern UI, incorporating glass morphism, animated gradients, and dark mode support for an immersive user experience. It also includes Google Analytics for tracking usage and Google AdSense integration for potential monetization.
What I Built
Frontend Development: Built a modern, responsive UI with TailwindCSS and interactive animations.
JavaScript Logic: Implemented password generation, strength analysis, copy-to-clipboard, and history tracking.
Dark Mode Implementation: Added localStorage-based dark mode toggle for persistent theme settings.
SEO & Structured Data: Optimised meta tags, schema.org structured data, and Google Analytics tracking.
Performance Optimisation: Minimised CSS and JavaScript payloads for fast page loads.
Google AdSense & Analytics: Integrated Google services for tracking and potential monetisation.

Challenges & Decisions
Ensuring Secure Randomisation: Implementing a robust password generation algorithm that avoids predictable patterns.
Real-Time Strength Analysis: Calculating password entropy dynamically to provide accurate security feedback.
Smooth UI/UX Design: Implementing animated gradients, glassmorphism UI effects, and smooth transitions for a modern experience.
Dark Mode Implementation: Ensuring a seamless light/dark mode switch with localStorage-based persistence.
Clipboard & Export Functionality: Implementing copy-to-clipboard with tooltip feedback and a CSV export feature for saving generated passwords.
SEO & Performance Optimisation: Ensuring fast load times, meta-tag optimisation, and structured data implementation for search visibility.
AdSense & Analytics Integration: Integrating Google AdSense for potential monetization and Google Analytics for user tracking.
Impact

User-Friendly Experience: Features real-time password strength analysis, smooth UI, and mobile responsiveness.
Time-Saving Automation: Users can quickly generate, copy, and export passwords without manual effort.
Dark Mode for Accessibility: Provides aesthetic and accessibility improvements for different lighting preferences.
Potential for Monetisation: Includes Google AdSense integration for potential revenue generation.
What This Proved
Password Entropy Calculation: Learned how to measure password strength based on character diversity and length.
Clipboard API & Copy Feedback: Implemented a user-friendly password copying feature with a tooltip notification.
Dark Mode State Persistence: Used localStorage to remember user preferences across sessions.
Exporting Data to CSV: Gained experience in converting JavaScript data into a downloadable CSV file.
UI Enhancements with TailwindCSS: Applied glassmorphism effects, animated gradients, and interactive button effects for a visually appealing UI.
Web Performance Optimisation: Improved load speeds with lazy loading, optimized CSS, and minimal JavaScript.
