Mojang’s Tobias Mollstam has announced on the official company blog that user accounts for Minecraft, Cobalt and Scrolls will only require one sign-in. According to the post, once users create a Mojang account they will be able to use this universal sign in for the aforementioned titles. Basically, it’ll work in a similar fashion to Battlenet. Those who have an existing Minecraft account aren’t being forced into this, as it’s opt in only at this point. Thanks, Gamefront.
