Exactly why it's a default action to have your Microsoft Account email address shown on your dashboard is a bit of a mystery, but there are some very legitimate concerns with it being there.
If you're a streamer or content creator, for example, the last thing you need is for your viewers to catch a glimpse of your Microsoft Account on screen because it's just rotating there in the top corner of your dashboard should you happen to go there.
Fortunately, while it might not need to be there in the first place, you can at least turn it off. Here's how.
Note: The images here are from the newest Xbox One experience, however, the process remains the same for the older one, too.
- Press the guide button on your controller.
- The first menu item is accounts.
Select sign-in, security and passkey.
Uncheck the box next to show on home where you'll also see your email address.
That's all you need to do in settings, now head back to your home screen and check the top right-hand corner. Where once you saw your name with your email address beneath on rotation with your Gamertag, you'll now just see your name as in the image below.
A number of the Xbox community members have been questioning this very issue, but thankfully it's a very simple process to make it go away.
