Why avoid "easy" PINs
A small number of PINs cover a large share of real ones: runs like 1234, repeats like 1111, patterns like 1212, and years people were born. Someone guessing a PIN tries those first. This generator picks digits at random and throws away anything on that list.
Four, six or eight digits?
Every extra digit makes guessing ten times harder. Use six digits where a device or card allows it, and store the PIN in your password manager so you do not have to reuse one.
