Your IGN (Ingame username) is the username you used to register your minecraft account with. For example if you registered the name fluffy bunny when you bought. Minecraft it would be fluffy bunny. Hope that helps!

The

Your IGN is your in game name, in this case it will be your minecraft player name.
