google drive access requires pin?

I’m trying to set up google drive access in LO 5.2.1.1. But the sequences brings me to a dialog requiring a PIN. I have no idea what that is about. I don’t recall ever setting up a PIN with google drive, and can’t see any place there for doing so.

same problem here
this feature is nice, but needs some work
I can’t use it currently, i’ve tried everything.
