Email liability waiver kiosk without PIN requirement

Issue:  Someone reserves multiple courts for a group event and most if not all attendees have never been to the club, and may never come again.  We still need to have them sign our liability waiver but we don't want to require them to go through the entire profile setup process (we require a payment profile as well).  There is usually one point of contact for the group we are dealing with.

We can create a kiosk to sign our waiver that produces a URL that can then be copied into an email.  

Problem to Solve:  When the recipient clicks on the URL they are asked for a PIN to sign into the kiosk. I want this requirement eliminated so they go directly to the guest waiver form without entering a PIN.
