FAQ
Is my password sent to any server?
No. The entire analysis runs directly in your browser using JavaScript. Your password is never uploaded, stored or transmitted, so there is no risk of a leak.
What is password entropy and why does it matter?
Entropy in bits measures how unpredictable a password is. The higher the value, the more guesses an attacker would need. A longer password using more character classes has higher entropy and a longer estimated crack time.
