You need to pay a close attention to the security of your passwords. A security PIN number that has 4 characters and minimum 4 digits is a number that has at least 4 characters between 'a' to 'Z' and minimum 4 digits between '0' to '9'. This is mandatory because using numbers and letters in a password will increase its strength and will be harder to crack.
