Linux Debian12 How to bypass login and password?

[Jester]

I'm a total Linux newbie, so please bear with me....

I have installed LinuxCNC 2.91 under Debian12. Everytime the machine starts I need to enter username and password. This PC will be dedicated to a milling machine and will only be by used by me, and will probably not be connected to the internet so it would be more convenient if on power-up the login and password screen would simply be bypassed. I did find one reference stating to modify
lightdm.conf

So I opened a command prompt and typed "sudo nano /etc/lightdm/lightdm.conf" and then removed (under the "[Seat:*]" section,  the '#' for the following two lines (I assume the # means comment) and added my user name after =

Changed.....

#autologin-user=
#autologin-user-timeout=0

to

autologin-user=myusername
autologin-user-timeout=0

I then did ^O, and ^X the file appears to have been updated, because when I reopen the file I can see my changes.
This does NOT seem to work and does not address the password aspect.

myusername is my actual username

Suggestions welcome.

Do you run the LightDM window manager? If yes, have you also set up the autologin group? Please see https://wiki.archlinux.org/title/LightDM#Enabling_autologin.
