Create a free Mojang account, formerly known as a Minecraft account, by visiting Minecraft.net, clicking on the Register link in the upper-right corner of the page and entering in the necessary personal information. Though the account is free, you need to purchase a copy of the game to play.
The online virtual building game "Minecraft" is owned by the company Mojang. In November 2012, the company renamed its online account system to match the company name and account for the creation of other games, thus avoiding confusion for future players. Creating a Mojang account involves registering a valid email address with the company, creating a password and entering your date of birth to verify that you are old enough to play. After entering in this information, you need to confirm the email address by following the instructions in the registration email that arrives shortly after submitting the information.
After registering the account, you can enter payment information to purchase a copy of "Minecraft" to play on a computer. The video game console versions, as well as smart phone and tablet versions, of the game are available to purchase through each device's respective virtual store. Creating the account allows you to manage your characters and information across the various platforms on which you play the game.
