Newbie here. I want to create a guest account on my system. I tried using the gui application, but when I opened it, it did not give me the option to create a new account, likely because I am not root. (I was not prompted for the sudo password like I thought I would be.) I then tried it using the sudo adduser command and was successful. However, when I login as the new account there seems to be no permissions enforcement as I can view my master account's directories and files.
Any ideas on how to fix this?
