Why
How long would a computer need to guess your password if it tried everything one by one?
A four-digit PIN has only 10,000 possibilities. A computer tries them all in the blink of an eye.
With every character you add, the number of possibilities gets much bigger. That is why a long password is so much stronger than a short one, even though the difference looks small.
