Why This Is Secure

This generator uses crypto.getRandomValues() — the browser's cryptographically secure random number generator, which is designed to be unpredictable even against adversaries. It uses rejection sampling to eliminate modulo bias, ensuring every character in the pool has an exactly equal chance of being selected.

🔒 crypto.getRandomValues()

✓ No modulo bias

✓ Zero server transmission
