You only have to buy Minecraft once. Minecraft is linked to your Mojang account, which means that once you purchase the game, it is tied to your account and you can download and install it on any computer that you log in to with your Mojang account.
To download Minecraft on another computer, you will first need to log in to your Mojang account. You can do this by visiting the Mojang website (www.mojang.com) and clicking on the “Log In” button at the top right corner of the page. Enter your Mojang account email address and password, and then click “Log In.”
Once you are logged in, you will be able to access your Mojang account dashboard. Here, you will find a list of games associated with your account, including Minecraft. Click on the Minecraft icon or name to access the Minecraft download page.
On the Minecraft download page, you will see options for different platforms and editions of the game. Choose the appropriate version for the computer you want to install Minecraft on. For example, if you want to install Minecraft on a Windows PC, click on the “Windows” option. If you want to install it on a Mac, click on the “Mac” option.
After selecting the correct version, click on the download link to start downloading the Minecraft installation file. Once the download is complete, open the file and follow the on-screen instructions to install Minecraft on your computer.
During the installation process, you may be asked to log in to your Mojang account again to verify your ownership of the game. Simply enter your Mojang account credentials when prompted, and the installation will proceed.
Once Minecraft is installed, you can launch the game and log in using your Mojang account to start playing. Your game progress and saved worlds are also tied to your Mojang account, so you can access them from any computer where you have Minecraft installed.
You only need to purchase Minecraft once, and it is linked to your Mojang account. You can log in to your account on another computer and download and install Minecraft without having to buy it again. Just make sure you have an active Internet connection and your Mojang account credentials handy.
