Disable Autologin in lubuntu 20.4

How to disable autologin in Lubuntu 20.04. I installed Lubuntu 20.04 recently. It works great but my only issue is when I power on the system, it directly lands on desktop, without asking password or any login screen. I want to disable autologin, how to do this

try with editing the sddm config file
/etc/sddm.conf
and remove the line
User=you
