Nintendo has announced that Google and Apple account support for Nintendo Account’s “Easy Sign-In” feature will officially end on January 26, 2027. With no other accounts supported by Easy Sign-In, the feature itself will also be discontinued.

Easy Sign-In lets users access their Nintendo Account using their Google or Apple account credentials, offering many players a convenient way to sign in.
Once account linking support ends, users will no longer be able to sign in with those credentials or create a new Nintendo Account through the feature. The My Nintendo Platinum Points mission for linking a Google account will also be discontinued.

After the service ends, devices that are already signed in may continue working without requiring users to sign in again. However, if the sign-in screen reappears, users will need to choose one of the following methods:
- Nintendo Account email address or Sign-In ID and password
- Passkey
Anyone who has forgotten their password—or never set one up—can select “Forgot password” on the sign-in screen to reset it. If the registered email address is no longer accessible, users will not be able to change it themselves and must follow the instructions in Nintendo’s official Q&A to request an email address change.
Nintendo also recommends using a Passkey as an alternative to a password. This allows users to sign in with biometric authentication on a smart device, including fingerprint or facial recognition. According to Nintendo, it offers an easier and more secure way to access an account.

Players should check whether they currently rely on Easy Sign-In. Once the feature is removed, another sign-in method will be required, so setting one up in advance could prevent confusion later.
