To unlink your EA account from your Xbox account, follow these steps:

1. Go to the EA Account settings portal by signing in at ea.com.
2. Once logged in, click on your profile icon at the top right and select "Account Settings."
3. In the Account Settings, navigate to the "Connections" tab.
4. Find the Xbox account listed under your connected platforms.
5. Click the "Unlink" button next to the Xbox account.
6. For security verification, EA will send a security code to your registered email. Retrieve the code from your email and enter it on the site.
7. Confirm the unlinking by checking the confirmation box and clicking "Unlink" again.

Important notes:

• Unlinking creates a permanent change for six months where you cannot relink a different Xbox gamertag to the same EA account.
• If your EA account has been inactive or deactivated, unlinking may be complicated or require contacting EA support.
• Be sure that unlinking will not cause you to lose important game progress or data.
• If you encounter difficulties, contacting EA support can help resolve issues.

These steps should allow you to unlink your EA account from Xbox safely and securely.
