Password Generator

Random passwords and passphrases from the browser's cryptographic RNG. Nothing is sent anywhere — the page makes no network requests after it loads.

entropy 0 bits · alphabet

Estimated time to crack offline at 10¹¹ guesses per second: . Entropy assumes every character is chosen independently at random, which it is.

Generated in your browser, never sent. Values come from crypto.getRandomValues(). Nothing is logged, stored or transmitted — reload the page and it is gone.

from the command line

shell
curl -s https://passwd.monster

Scripts get one 20-character alphanumeric password as plain text. That request is answered by the server, so unlike the generator above it does leave your machine.
