I am running Gentoo Linux with XFCE4 as my desktop environment. I have roughly the same setup on my desktop and laptop. On my desktop, whenever I open a terminal window from within the desktop environment (I tried the default terminal and xterm), it asks for my password before I can use the terminal. This doesn’t happen on the laptop, but I don’t know what I did to stop it.
Why does the terminal ask me for my password? Is there anything I can do to stop it? (And, indeed, should I want to stop it?)
