About PassGen
Secure passwords, simplified.
Crypto-Random
PassGen uses the Web Crypto API (crypto.getRandomValues) — the same standard used by browsers for cryptographic operations. Not Math.random().
4 Tools in One
Password Generator (with custom rules), Strength Checker (with entropy & crack time), Passphrase Generator, and Bulk Generator (up to 50 at once).
Strength Analysis
The checker shows entropy in bits, estimated crack time at 100 billion guesses/second, and specific suggestions to improve your password.
Privacy
Everything runs in your browser. No passwords are ever sent to any server — not even as analytics events.
