If you are looking to share an Xbox Series X/S with someone and need to set up another account, there is one main way to do so.
This will likely be most common for a family group sharing the same console, but this could also be used by roommates or similar people who are both using the same console.
You will want to follow the instructions closely, as otherwise you could get some odd error codes or do something you didn’t mean to do.
There were some great games on Xbox in 2024, and even more are coming this year. If you want to be able to enjoy your games while someone else plays theirs on a different account, you will have to make sure you both have separate accounts.
This means you will have separate games, separate save states, and separate achievements. This means no one has to get upset that another household member accidentally deleted a save file or a game.
