Hey Zhanglongjiao,
If you have FC 26 on Steam, and you unlink your account, you won't be able to access your Ultimate Team anymore via the Steam platform. If you then link your Steam to a new EA account you'll have to make a fresh UT.
Furthermore, there are risks when you unlink an account:
If the platform account you use to play EA SPORTS FC™ is still set as active in the Web and Companion Apps when you unlink, you'll lose access to the apps.
If you have more than one platform account on your EA Account that you use to play EA SPORTS FC™, you can change which one is active in the Web and Companion Apps to greatly reduce the risk of losing access to the apps.
The risk is much lower, but still exists. Don't unlink your platform accounts if you want to be sure you can always access the Web and Companion Apps.If you’re sure you’re okay with this risk, here’s how to switch accounts in the apps:
- Sign in to the Web App or Companion App.
- Select Settings.
- At the top right, select Change beside the platform icon.
- Choose the platform account you want to set as active—it shouldn’t be the one you’re planning to unlink.
