My Nintendo signups / pre-registration is now live so players can go ahead and opt-in for free. Nintendo Account is a new multi-platform account system introduced by the company to improve user experience and make content and features more accessible. My Nintendo is a built-in reward system of the platform.
You get an account by registering with your Nintendo Network ID, Facebook, Google+ or Twitter accounts. Signing up is pretty straightforward, however, since the service isn’t fully operational for the time being there isn’t much to do.
Next month, Nintendo will also launch a companion app for Nintendo Account, Miitomo. Registration for the app is also live now, you can visit the official website to sign-up, but the app itself will release in March.
