FAQ
Why passphrases instead of random passwords?
Passphrases are easier to remember and type on mobile while still delivering high entropy. Four random words already exceeds the strength of most user-chosen passwords.
Are the words picked cryptographically?
Yes. We use crypto.getRandomValues to pick each word from a curated dictionary.
Is my passphrase sent anywhere?
Never. Everything runs locally in your browser and no passphrase is transmitted or stored.
