In ArchLinux utilize polkit to allow suspending from cli after locking the screen

49-suspend_nopass.rules

// Make sure user is in wheel group (usermod -aG wheel user
// After that add this file under  /etc/polkit-1/rules.d/49-suspend_nopass.rules
// Then running (replacing dm-tool lock, with your locker):  dm-tool lock; sleep 2; systemctl suspend
// Will lock the screen and then suspend, no more people seeing random shit on you.
//yay!

polkit.addRule(function(action, subject) {
	if ((action.id == "org.freedesktop.login1.suspend" ||
		action.id == "org.freedesktop.login1.set-wall-message") &&
		subject.isInGroup("wheel")) 
	{
		return polkit.Result.YES;
	}
});
