Frequently asked questions

What length PIN should I use?
4-digit PINs are standard for bank cards. For app or device PINs, 6 digits provides significantly more security.
Is the PIN truly random?
The PIN is generated using Math.random() — sufficient for typical use but not for high-security cryptographic applications.
Why is 10 the max when avoiding repeats?
There are only 10 unique digits (0–9), so a 10-digit PIN without repeats uses them all. A longer unique PIN is impossible.
