A Nintendo Account may be deleted if it is inactive for more than six months. All data connected to the account, such as mission status, points and rewards in the My Nintendo rewards program will be lost if it is deactivated. App data saved with your account.
A Nintendo Account cannot be removed from a Switch console once it has been linked to one. The account and all of the purchases are preserved after unlinking it. In the future, you may re-link another user account to the same Nintendo Account.
Select System Settings from the HOME Menu. Select Data Management and Delete Serial Save Data from the drop-down menu. For each game title for which you wish to remove save data, choose it from the drop-down menu. If any is available, select it or else Delete All Save Data for this Software.
Purchases on the Nintendo Switch eShop are linked to your own Nintendo Account, which made the purchase. You may access a digital game that you’ve purchased with your Nintendo Account on any other Nintendo Switch console (primary or non-primary).
You may utilize your Nintendo Account to play games on multiple Nintendo Switch consoles, linked to the same account. You can use your Nintendo Account to link up several systems and play games on any of them. Only one of the consoles is allowed to be the primary device. Any additional users can play the games you downloaded with your account on the primary system.
