If your organisation has PIN number login enabled, when you log in the system will ask you to input 3 randomly selected digits from your PIN. You will see something like the screenshot below.
For example, you might be asked for the third, second and first number from your PIN. In this case if your PIN was 562548 you should enter 2 (third digit) in the first box, 6 (second digit) in the second box and 5 (first digit) in the third box.
