Frequently asked questions
Are these passwords stored or transmitted?
No. They are generated on your device with crypto.getRandomValues and exist only on this page until you close or refresh it.
How long should a password be?
For random passwords, 16 or more characters is a good default. For passphrases, use at least 5 words from the 2,048-word list (about 55 bits) and 6 or more for important accounts.
