Step by step instructions on linking your Twitter, Facebook, and/or Google accounts to your Nintendo Account. Notes:
You can also use your social media account to create a new Nintendo Account.
A Nintendo Account for a child cannot be linked to a social media account. These can be linked to a Nintendo Network ID only.
What to Do:
Go to the Nintendo Account website and sign in to your Nintendo Account.
Click User info, then scroll down to the Linked accounts section and click Edit. A list of all potential social media accounts will appear (Facebook, Twitter, Google, Apple ID).
Do you want to link a new social media site or unlink an existing social media site from your Nintendo Account?
Link a New Social Media Account
Click the box next to the service you want to link (Facebook, Google, Apple ID or Twitter).
Follow the onscreen steps to validate and complete the link.
Unlink Existing Social Media Account
Click the checkmark next to the appropriate service to remove the link.
If you created your Nintendo Account with the social media site that you are removing, you will need to link an additional service (Facebook, Twitter, Google, Apple ID) OR create a Nintendo Account password before you can remove the link.
