KIOSK PIN

KIOSK PIN

I'm uncertain about how to use the KIOSK PIN.  I have the app downloaded onto my iPad.  
I have no front desk staff so I do not want to use the "hand over" feature.  Based on the description provided, it appears there is a way to generate a PIN for patients to login to the app & update information, answer questionnaires, etc.  
Can anyone here provide guidance on how to utilize the KIOSK PIN feature? 
Thank you
