Passcode protect a Pass
If this is a Pass that maybe has a special price attached, or perhaps you only want to have it available to a select group of patrons (like donors or VIPs) you can have that pass available only through passcode. By enabling the Passcode for a specific pass, only those with the code will be able to access that pass (whether it's a season ticket, flex pass, or membership).
To accomplish setting this up, go to More (at the top of your admin panel) -> Passes -> Edit (next to the Pass you would like this enabled the passcode on). Once there, scroll down to the bottom of the pass where you will see "Special Passcode". At this point, you can enter your passcode and select "Save Changes" for it to be saved.
Once saved, the passcode will be required by any patron wishing to purchase that pass type, as seen below. This will not require a passcode on the admin site.
