You can choose whether to make a user an admin, and you can specify certain dashboards to be admin only. My wall panels are all logged in with a non-admin user specific to that panel, set to show only what I want anyone to access.
Some of us in the family are logged into dashboards on our phones with different users, which update depending on which room we are in.
If you want to gate access to certain functionality on a dashboard designed for a common area, you would need to route to a different dashboard upon providing some kind of authorisation, e.g. an onscreen PIN pad.
Happy to discuss.
