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

A 5-word passphrase from a 52-word list is easy to type but weaker than it looks — raise the word count for anything that matters.
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
curl -s https://passwd.monster
