Playing online with Mojang's authentication will always require you to have a premium account.Īnyone suffering from this issue should purchase the game and experience every feature Minecraft has to offer, including custom skins. Some players who pirated Minecraft regularly post on forums asking if they have a Minecraft skin bug, but it usually boils down to them not realizing that they are basically playing in offline mode. If you have a pirated version of Minecraft and don't have an active Mojang account, then your skin simply won't show.
This can cause Minecraft to check which skin you want and could potentially lead to your skins tab not being updated. If your skin still hasn't been updated, the second-best option would be to restart your Minecraft game.
