Where do you find the library pin for hoopla?

But where is the pin on your card?

I was able to log into Hoopla via the app without a code. Instead, I searched 'Bourbonnais Public Library'. I then used my library card and PIN to log in for that. Hope this helps! Edit: I just saw your reply. Your default PIN is the last four digits of your library card. I suggest getting a member of the staff at the Information Desk to help you, or go to one of their numerous workshops to learn how to use it.
