Managing PIN codes
Warning
The PIN code protects access to your smart card.
It is asked whenever you access your smart card.
There are two levels of protection codes:
PIN code: the normal access PIN code. The PIN code should be easy to remind and should be learned by heart. Usually it
contains only numbers. If you live in Europe and use a credit card, this is the equivalent of your credit card PIN number.
PUK code: personal unblocking code used when the PIN code was lost. You should always code down you PUK code and
keep it in a safe place. In a production environment, it should be very log to protect against brute force attack.
Listing PIN codes
