Common questions

Are these passwords actually random?+

They come from the browser’s cryptographic random number generator, not Math.random(), which is seeded predictably and must never generate a password. Characters are drawn with rejection sampling so no part of the alphabet is favoured.

How long should a password be?+

Long enough to clear about 80 bits of entropy, which the meter here shows as you adjust the length. With all four character sets that is roughly 13 characters; with lowercase only it takes about 18.

Is the generated password sent anywhere?+

No. It is produced in your browser, never transmitted, and never stored — reloading the page loses it entirely.
