Steam Guard.
Hi guys. One of my friend buy for me CSGO but now steam ask me a code...but I don't get my keycode by email ...
Did your friend buy an account which has CS:GO on it or did he gift you the game?
Check you spam folder and make sure your on the right email if none work just wait alittle while you should get one shortly
You need to provide more information than that. Are you trying to login to Steam from a new computer? Is your friend buying the game for you? Did your friend buy an account that has the game on it?
