Frequently Asked Questions

Are generated passwords stored or logged anywhere?

Absolutely not. Passwords are generated strictly client-side using the Web Crypto API (crypto.getRandomValues) and never leave your browser memory.

What is the recommended password length for optimal security?

Security standards recommend at least 16 characters mixing uppercase, lowercase, numbers, and symbols to resist modern GPU-accelerated brute-force attacks.
