Frequently asked questions
Is the password sent anywhere?
No. It is generated on your device and never leaves your browser. Reloading the page discards it.
Is this randomness secure?
Yes. It uses crypto.getRandomValues(), a cryptographically secure pseudo-random number generator, not Math.random().
What length should I use?
16 characters or more is a good default. Use the maximum a site allows for important accounts.
