I just started to install Antergos Xfce to an old laptop. I want to use it for education purposes in our school. Actually there are mostly Windows devices but I got 40 old Lenovo laptops and want to bring Linux to the school :) Everything works and looks fine at the moment - but I have a question about possibility for users to retrive wifi passwords. That would be a big security issue and would kill the project…

I have created an user account without sudo possibility and the user is not member in “wheel”. So he cannot access /etc/NetworkManager/system-connections directory where passwords are stored in plain text. This looks good. But is there any other possibility for a user without any root access to get knowledge of the wifi passwords?
