Frequently Asked Questions

How random are these passwords?▾
Passwords use Math.random() which is a pseudo-random number generator seeded by the browser. For maximum security, use a dedicated password manager which may use cryptographically secure randomness.
How long should my password be?▾
NIST guidelines recommend at least 12 characters. 16+ characters is better. Length contributes more to security than complexity — a 20-char lowercase password is harder to crack than an 8-char complex one.
Are generated passwords stored?▾
No — all generation happens in your browser. Nothing is sent to any server. Refresh the page and the passwords are gone.
