Random PIN generator
People choose PINs badly: 1234, birth years and repeated digits make up a large share of all codes in use. A random PIN removes the pattern. This page presets 6-digit PINs generated with cryptographic randomness; change the length to 4 or 8 to match your card, phone or alarm panel.

Tips
- Avoid PINs that are also dates or that repeat digits; the generator never favours any digit, but you may reject a code that looks memorable to others.
- For phone unlock codes, 6 digits are the minimum worth using; prefer an alphanumeric passcode where possible.
- Write the PIN only in a password manager, never on the card.

Frequently asked questions
- How random are these PINs?
- They use the Web Crypto API with uniform sampling, so each digit is equally likely.
- Can a 4-digit PIN be secure?
- Only with a lockout after a few wrong attempts, which cards and phones have. For anything without lockout, use a long password.
