Access restrictions to account

Hi,
I just installes one essentials. The problem is:
We administrate multiple mashines and these mashine can be Administrated by our customers also.
So when we connect our account to the software, every mashine has administrative access to our account, right?

Thats not a good idea.
Or am I wrong?

Thanks!

Ahhh nonono,
I just saw my false.
When I log out in the Browser the problem is solved.

Thanks anyway.
please close.
