Hi Dyanna,
Thank you for using the Cvent Community !
You are correct in your thinking. The Passkey link will only work when the event is in active status. Since the event is in test mode, we can control the information and how to clear it out when we launch the event, but we do not have the Passkey instance in a test mode so it's a safe keeping to ensure you are not having test hotel data be sent through your Passkey instance.
If you have any additional questions on this, please reference the Passkey Integration Guide in the Cvent Community.
Best,
Morgan
