Multiples questions about Unreal Engine 4 from a beginner

Thanks for your answer.

I’ll watch the video serie.

And GarnerP57, i’m interested to put my incoming game on Steam. But how am i suppose to proceed ? It would mean that i interact with their server. It seems to make it even more complex.

I thought to deal with password i only had to crypt it with hash function that already exist.

EDIT : it seems like, since i’m using Unreal Engine 4.17, it already have steamwork sdk. Where could i find documentation about how to use steam on U.E. ?
