How this tool works
Randomness comes from the browser’s cryptographic generator with rejection sampling. Each requested password is independent. The entropy estimate includes the selected character-set requirement. Offline crack time is a rough average at 10 billion guesses per second, not a guarantee.
Input and output stay in the current page. Refreshing or closing the page clears them. For very large inputs, use Run to start processing; a task that takes too long is stopped so you can change the input.
Frequently asked questions
Are passwords stored or sent anywhere?
No. The browser generates them locally. Copy or download only when you choose.
What if no character set is selected?
Generation stops with a message. Select at least one set and generate again.
