How can I have two different profiles, with two different skins, in Minecraft? My two daughters want to play, and I don't want to download two copies of the game, or buy two accounts. They would be playing from different computers, too.
At the moment, you get one user preferences account. You can set one skin per user at a time.
You can easily change skins online but it would still be the same user and all that entails.
Additionally, using the same account on two computers, although possible, is not advisable and in many cases not allowed. This is especially problematic if they try to connect to the same server or to play together on a LAN.
That all said, the best solution is to acquire a second account.
