Frequently asked questions
How random are these passwords?
They come from crypto.getRandomValues — your browser's cryptographically secure random number generator, the same class of randomness used for encryption keys. No Math.random() shortcuts.
Are generated passwords stored or sent anywhere?
Never. Generation happens entirely in your browser's memory — passwords are not logged, stored, or transmitted, and they disappear when you leave the page.
What does the entropy meter mean?
Entropy measures how hard a password is to brute-force, in bits. Each extra bit doubles the search space — aim for 80+ bits for important accounts.
What does "exclude ambiguous characters" do?
It removes lookalikes such as O/0 and I/l/1 so the password is easy to read out or retype from paper without confusion.
