Logging in with Steam​

  • First we need to request a Encrypted App Ticket from Steam so that we can authenticate with EOS. In this example we're going to use the SteamCore PRO Plugin plugin to retrieve a Encrypted App Ticket from Steam that we can use to authenticate.

  • SteamCore PRO Plugin on the Unreal Marketplace

  • After Receiving a Encrypted App Ticket from Steam, we will attempt to login with the Ticket but if this is your first time connecting then you will get a failure with “Invalid User” as a result, all you need to do then is to call Create User (one time process), after the user has been created you should be able to login.

Using SteamCore PRO and EOSCore together (DefaultEngine.ini)​

  • In addition to configuring SteamCore PRO plugin you'll need to set the NativePlatformService to SteamCore which allows the SteamCore plugin to initialize.
