During installation of Lubuntu 19.04, there is an option to Log in automatically without asking for the password.
Unfortunately, I can't find this setting anymore after installation.
I searched on the net but couldn't find any similar issues.
is for 12.04 or lower and there is no directory named /etc/lxdm/ or /etc/lightdm/ in 19.04.
is for Ubuntu and there is no Automatic Login setting in User Accounts.
