Question

Why do websites require lengthy and complex passwords but credit cards only need a 4-number PIN?

In: Technology

Answer 1

Credit cards and most banks are on the 20th century. A bank I know provides the users with 7 digit codes (THEY DEFINE) but when you try to login they ask randomly for 3 of these digits. Piece of cake for those trying to hack the account, specially because they do not use zeros, so finding the correct code is just 1/512.
