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. ?
