Get the players steamID?

How do I get the local players steamID in blueprints? And how to access other steam API features?
Im guessing alot of steam API is not accessible from blueprints, if so, when can we expect to see this updated?

Im trying to figure out some sort of player account / login system using the players steamID, and would also like to store player specific variables/stats.

Thanks in advance!

I just came across this thread
There seem to be various ways in c++ to achive this, but im not sure any of this is accessible from blueprints?
Anyone have any advice?
