Is this actually random?

Yes. Each digit comes from crypto.getRandomValues(), the Web Crypto API's cryptographically secure random number generator — not Math.random(), which isn't suitable for anything security-related like PINs or passwords.

Are the PINs sent anywhere?

No. Everything is generated locally in your browser with JavaScript — nothing is transmitted, logged, or stored. Refreshing or closing the tab makes them disappear for good.

What does "avoid adjacent repeating digits" do?

It re-rolls a PIN if any two digits next to each other are the same (like the "11" in 4112), which some systems disallow or which people find easier to mistype. It's a filter on top of the same random generation, not a separate weaker method.

What length should I use for a bank card or phone PIN?

Most card and device PINs are 4 or 6 digits — set the length slider to match what the system you're setting it up for requires. Avoid picking a PIN yourself that matches a birthday or repeated pattern; a generated one avoids that automatically.
