Never tell

Keeping your PIN secure requires that only you know the number. Although you might give your PIN to friends or family that you trust in order to take money out for you, this is a bad idea. The more people who know your PIN, then the more likely you are to have the PIN discovered. Also, never give your PIN out over any communications such as email, as your bank will never ask you for this. Keep your PIN private and it should stay that way.
