Are these passwords really random?

Yes. They come from crypto.getRandomValues(), the same source browsers use for cryptographic keys — not from Math.random().

Do you store the passwords I generate?

No. They are created in your tab and never sent anywhere. Reloading the page loses them permanently.

How long should a password be?

16 random characters is comfortably strong for normal accounts. For a master password or crypto wallet, use 24 or more.
