Web Crypto API Hardware Security
Our generator uses `window.crypto.getRandomValues()` directly from your device operating system to generate cryptographically unbiased random entropy. Passwords are never sent over the internet or logged anywhere.
Entropy & Strength Evaluation
Evaluate password strength based on information entropy (bits of randomness), character pool size, and length. Get clear visual feedback on password complexity.
Frequently asked questions
Are generated passwords saved on your servers?
No! All password generation happens 100% inside your browser using client-side JavaScript. Nothing is sent to any server.
What makes a password strong?
A strong password has at least 16 characters, combines uppercase, lowercase, numbers, and symbols, and avoids dictionary words or repeating patterns.
