Ever since the intro of Grub2,
on the main Log-in screen, there is a "User"
listed at the bottom of whoever is listed on the Users Log-in.
Just what or who is this used for?.
if it is 'clicked' on, then it asks for a password,
as if 'it' is some kind of "user".
But, as I don't know just what 'it' is for,
therefore I also don't know 'it's' password either.
