About Secure PIN Generator
The Secure PIN Generator creates 4, 6, or 8-digit PINs, or a custom length, from a cryptographically secure source, with an option to avoid repeated digits. It is for setting device, card, or app PINs that are not easily guessed.
People pick predictable PINs like birthdays or repeated digits. Generating one from a secure source locally gives an unguessable PIN with nothing transmitted.

- Choose a PIN length: 4, 6, 8, or custom.
- Optionally require that no digit repeats.
- Generate the PIN from the secure random source.
- Generate again if you want an alternative.
- Memorise it or store it securely.
