One M7 Sense 6 and lock screen widgets

I’ve seen posts like “I lost my lock screen widgets with Sense 6!!”. No, not really. It’s still there.

But in Sense 6, the Enable lock screen widgets setting is by default disabled (as in AOSP Android) so you have to Enable it first. And then it work as before.

Where do I change that? 
Settings > Security > Enable lock screen widgets
