Hey Product Hunt! 👋 I built QPasswordStrong because I kept reading about quantum computing threats and realized nobody was explaining it to normal people in a simple way. Most password checkers tell you "weak" or "strong" based on old rules. But quantum computers change everything thanks to Grover's algorithm, they can effectively halve the security of any password. An 8-character password that would take a classical computer 400 years to crack? A quantum computer does it in minutes. So I built a tool that shows you two crack times side by side, classical and quantum, so you can actually see the difference and understand what "quantum-safe" really means. A few things I'm proud of: 🔒 Your password never leaves your browser — everything runs locally in JavaScript ⚛️ Real Grover's algorithm math, not made-up scores 🛡️ A "Quantum-Safe" rating for passwords with enough entropy to survive the quantum era Completely free, no account needed Would love your feedback, especially from anyone in security who wants to poke holes in the quantum crack time model. Happy to discuss the math! 🙏
