FAQs
How random are the passwords?
They use your browser's cryptographically secure random generator (Web Crypto), the same kind used for encryption keys.
Do you see or store my passwords?
No. They're created on your device and never sent anywhere or logged.
How long should a password be?
At least 12 characters; 16+ with mixed character types is very strong. Use a different password for every site.
Is anything sent to a server?
No. Everything is calculated in your browser, so it works instantly and nothing you enter is stored.
