I am trying to figure out authentication and how our clusters are unique. We added a user of the same name, we all have the same password, and whitelisted any IP addresses. Our clusters have the same name, and when connecting via Compass, the Hostname of my sandbox cluster seems pretty generic. Also, when going into the Atlas Cloud dashboard, I see up to 7 connections in my newly-created cluster. What is keeping others from going into my cluster and modifying the contents? And if I’m the only one in, why are there so many connections?
