game tag.

Hi stellasteve1,

Thanks for your post. Here's an article on
How to sign in to separate apps using different Microsoft accounts. This should allow you to choose and change the account used for the game.

Let us know how this goes, thanks again.

Is this for Modern Warfare because your display name is your Activision ID.

Hello Ron,

Thanks for coming to the forums. Is the Houdini202 an old gamer tag of yours? The reason why it is showing is you play on Activision account for Call of duty games. You will need to update the gamer tag with Activision, for it to show the correct gamer tag.

Thanks,

Brad

Hi there, PolezneyNa95.

We're afraid that if you're seeing that, that means your one-time free gamertag change was already used by your account. A one-time free gamertag change is only provided to an account if their gamertag was automatically selected for them when they joined
Xbox Live. If you received an auto-generated gamertag and changed your gamertag once before, that would have been your free change and you would not be eligible for another one.

Hello!

Once you're signed in, you should be able to click on the gamertag/player and sign in as a different one.
