Admin / installer / setup person can see all content?

Administrator privileges give access to all dara.  That’s fairly universal for an operating system.  And rather an essential right for a true system admin.

I wonder if you set up another non-admin account for yourself, and then use larryg0’s trick of clearing credentials here:

would allow you to access only as a normal user.

Then you’d only have admin rights via the dashboard?

Not tried it, but it might be worth experimenting with.
