I thought this would be a common question but after searching for answers I couldn't find anything that addresses this exact problem.
Anyway, I have an administrative password, so every time I want to install an update or gain root privilege, I am asked to enter it. However, I want to set this password for logging in so other people can't access my account (which is the only account on my laptop). I went to: 'System Tools' > 'Users & Groups' and in the [Users Settings] window it is supposedly set like this 'Password: asked on login' But this is not the case because it never requests my password when I log in. How do I solve this?
