Are these PINs cryptographically secure?

Yes. Each digit is drawn from the browser's crypto.getRandomValues generator using rejection sampling, which removes modulo bias so every digit is uniformly random.

How accurate is the randomness?

The tool uses the Web Crypto API's CSPRNG and rejects values above the largest multiple of ten that fits in a 32-bit integer, guaranteeing an unbiased uniform distribution across digits 0-9.

Is my PIN sent anywhere?

No. PINs are generated entirely in your browser. Nothing is transmitted over the network or saved.
