Is it possible to use Lutris without logging in?

I recently got a new computer and that means reinstalling old games I had via Lutris.

A lot has changed and one thing I don’t like is that Lutris is forcing me to log in to my GOG store. I don’t want to.

Looking at some of the install scripts, they seem to require you to log in (such as Mark of the Ninja remastered). Fair enough.

But there are plenty of old installation scripts that don’t have this requirement (ie Fallout 3). Why can’t I use those old scripts to install a game without logging in?

Is there merely a setting or somehting I am unaware of? Is there a solution to this?
