Frequently asked questions
How long should a password be?
Sixteen characters across mixed classes gives roughly 100 bits of entropy, which is comfortably beyond brute-force reach today.
Are generated passwords stored anywhere?
No. They are produced in your browser and never sent anywhere or written to storage.
