Not Another Password Generator
Generate passwords from real-world chaos, not Math.random()
Most generators fake randomness with Math.random(). NAPG fuses 13 real-world signals - mouse movement, network latency, hardware fingerprints, crypto bytes & more into a SHA-256 hash. 100% client side. No data leaves your browser.
Hey Product Hunt! 👋
I'm Aadarsh, and I built Not Another Password Generator — yes, I know, another password generator. But hear me out.
Most password generator I've ever used calls Math.random() under the hood. That's not cryptographic randomness - it's a deterministic function seeded by a timestamp. You're putting trust in something that's fundamentally predictable.
So I got a little obsessed. What if a password generator actually used real-world unpredictability as its source of truth?
NAPG fuses 13 live entropy signals on every single click:
- Your mouse movement (position, velocity, timing)
- Network round-trip latency (measured live via fetch)
- Hardware fingerprints (CPU cores, device memory, screen resolution)
- High-resolution timing jitter from performance.now()
- 128 bytes from crypto.getRandomValues()
...and more
All of it gets serialized and run through SHA-256 via the Web Crypto API, then used as a CSPRNG seed for character selection and a Fisher-Yates shuffle. Math.random() is never called, not even once.
A few things I'm proud of:
🔥 Burn After Reading - copy the password and a 30-second countdown begins before it auto-wipes
👁 Visibility toggle - passwords are masked by default
📊 Crack time estimator - tells you how long it'd take a GPU cluster to brute-force your password
🎨 Color-zoned slider - WEAK → STRONG → FORTRESS zones on the length selector
🌗 Light + dark mode - because of course
It's 100% client-side. No backend. No storage. No data ever leaves your browser. I built it with Claude in a weekend because I was annoyed, and then I couldn't stop adding features.
Would love your honest feedback — what would make this genuinely useful for you? What's missing? What's overkill?
