The information in this article can help you when you're unable to access the 2-step verification code required to log in to your Nintendo Account.
Note: Once 2-step verification is enabled, you will need to log in using BOTH your password and a 6-digit code sent to your smart device via the Google Authenticator app.
What to do
Launch the Google Authenticator application on your smart device. The 6-digit code is displayed on the app.
The app is required to set up the 2-step security feature, so you would have downloaded it when you set up 2-step verification for your Nintendo Account.
If the 6-digit code is not working on an Android phone, try using the Time sync feature:
Open the Google Authenticator app.
Tap the more options icon and then Settings.
Tap Time correction for codes.
Tap Sync now.
Click Enter backup code on the 2-Step Verification page during log-in, and enter one of your 10 backup codes.
10 backup codes were provided when the 2-step security was initially set up, with the direction to copy and save them to a safe place.
For general assistance with the Google Authenticator app, please see the Help & Feedback section of the application on your smart device.
Situation not resolved
If you do not have access to your backup codes or to the verification code on your smart device, you will not be able to log in to your Nintendo Account. Please contact us for additional assistance.
