I am struggling at the moment as my credit card and PayPal won't let me use them until they send me a text with a pass code. I ordered some stuff online yesterday afternoon and the pass code came through at 11 last night??Not necessarily before. But you need to insert it when you want to use it.
There is a gold metal touch pad on it. When you are asked for your authentication key plug it in (if it isn't already in) and touch the gold pad.
That is the entire procedure.
