FAQ

How are my passwords generated securely?

All passwords are generated 100% client-side using window.crypto.getRandomValues() with rejection sampling. No data is transmitted to any server.

What is entropy and how is it calculated?

Entropy measures randomness in bits. Higher entropy means exponentially stronger protection. 60+ bits is strong; 120+ bits is Beast mode.

What are Passphrases and why are they recommended?

Passphrases combine random words (e.g. correct-horse-battery-staple). Easier to remember while offering massive entropy.

Are generated passwords saved in my browser?

No. Passwords are never saved permanently. Only settings presets persist if you click Save Preset. Session history lives in memory and clears on refresh.
