Frequently asked questions

Are these passwords random?

Yes. They come from your browser's cryptographically secure random generator (crypto.getRandomValues), the same source used for encryption keys.

Are the passwords stored or sent anywhere?

No. They are created in your browser and disappear when you leave the page.

How long should a password be?

At least 16 characters for important accounts. Every extra character multiplies the number of guesses needed.
