Automatic login

[Junayeed Ahnaf via arch-general <arch-general@xxxxxxxxxxxxx>]

Hello,

How to enable automatic login in arch (using sddm and KDE) . 

I tried enabling it in /etc/sddm.conf but it didn't work. Also I saw 
something like getty but I didn't understand what it does or how to make it 
work. In all other linux there is an option called "user" in settings but 
that is absent in Arch.

Thanks in advance.
