About CreatePasswords

CreatePasswords is a free password generator with six engines: letters and digits, letters with symbols, pronounceable words, an anti-confusion set that leaves out 0 O o 1 l I, a fixed 8-character pattern, and RFC 4122 version 4 UUIDs. Choose the length and how many passwords you need, up to 1,000 at a time. A strength meter shows the entropy in bits and the estimated time to crack against attackers of different capabilities.

Random values come from crypto.getRandomValues, the cryptographically secure generator built into every modern browser, and are mapped onto the alphabet with rejection sampling so that every character is exactly equally likely. The page sets no cookies, loads no third-party code and runs no analytics, and its Content-Security-Policy rules out network requests of any kind. Switch your connection off and it keeps working.

Generated passwords can be copied, downloaded as .txt or .csv, blurred against onlookers and wiped automatically after a few minutes without interaction. The Password guidelines tab explains how to choose and handle passwords, and the Privacy & security tab describes what the page does and does not do, with a self-check you can run in your own browser.
