Your Nintendo Account will be destroyed permanently after the deactivation period has elapsed, and you’ll lose any data linked with it, such as Digital goods you bought in apps connected to your Nintendo Account.
Once a Nintendo Account is linked to a user account, it can’t be undone. A user account on a Nintendo Switch console will also erase any save data saved to the system as part of that account.
You may reactivate your account for a total of 30 days after it is disabled. The account will be permanently deleted and may not be resurrected once the 30-day period has elapsed.
To buy games in the Switch eShop, you’ll need a Nintendo Account. Purchases are linked to your Nintendo Account, which means that they’re accessible by anybody with a profile on your system. Up to eight accounts can be linked to one Switch unit, allowing up to eight people to play the games you’ve purchased.
Software is completely removed from your Switch and its icon when you delete it. This approach is ideal for individuals with a cluttered library who don’t expect to play the game again. However, if you know which game you wish to remove and have played it recently, all you have to do is select it on the home screen.
