Generates a random password or passphrase without leaving the page.
A single-page generator with length, character-class and word-count controls, from the company behind the open-source password manager. The page states plainly that generation happens locally with the browser's cryptographic randomness and that nothing is stored or transmitted, which is the claim that matters for a tool like this. Use it when you need one strong string and do not want to install anything.
