Instructions on registering a Nintendo Switch console as the primary console for your Nintendo Account.
Anyone that uses the primary console for your Nintendo Account can play the digital games that you’ve purchased with that Nintendo Account.
You can set one primary console per Nintendo Account.
When you sign in to your Nintendo Account on non-primary consoles, you will still be able to access digital games purchased with your Nintendo Account. However, other players will not be able to access your games on the non-primary console.
Complete These Steps:
Once you have signed in with a Nintendo Account, the first Nintendo Switch console you use to access Nintendo eShop will automatically be designated as your primary console.
If you want to change your primary console, you can de-register the current primary console. The primary status will automatically be set to whichever console you next use to access Nintendo eShop.
