I'm looking to create a landing page that allows Marketing Cloud users to check various data sources (data views, data extensions, etc.) for a specific subscriber. I understand how to do all this, but my concern is privacy. Realistically no one on the internet will figure out how to access the page, but it's a concern nonetheless. Should it be?
If so, is there a Marketing Cloud session variable to use to check log in status on the landing page? Is it possible to force that log in before accessing the landing page?
