If you already have an Ingress, Pokémon GO, or Harry Potter: Wizards Unite Account, we suggest signing up for Pikmin Bloom with a login method you already use. You’ll be able to link a Nintendo Account later. 
Currently, when starting Pikmin Bloom with a Nintendo Account, you won’t be able to link it with any login methods used for other Niantic games.

The Sign In with Nintendo Account method allows players to create an account on and log into the Pikmin Bloom using their Nintendo Account.

You may use the Sign in with Nintendo Account method as your primary sign in method, or you may use it in addition to Google, Facebook, and Apple Sign-in by linking the login method to the existing account.  Using a Nintendo Account as a login method enables you to import into the Pikmin Bloom your Mii that is created in a Nintendo account. Also, a special seedling will be granted to you once you link.

Please note:there are several limitations for using a Nintendo Account in Pikmin Bloom.
  • If you delete your Nintendo Account after linking it with Pikmin Bloom without having another login method, you will not be able to use the Pikmin Bloom data that was linked to it. However, if you reopen your Nintendo Account, you will be able to use it again.
  • You cannot link a Nintendo Account under supervised status to another sign in method. See “Linking an Additional Login Provider to Your Account” for more details.
  • Sign in with Nintendo Account is currently available only in the Pikmin Bloom and not on other Niantic products.

New Players

If you already have a Nintendo Account, you can use it to create a Pikmin Bloom account. Tap the Sign in with Nintendo Account button to create your new account on the Pikmin Bloom.

Existing Players

If you already have a Pikmin Bloom account, you can link it to your Nintendo Account in the game’s Settings menu. Once the Nintendo Account is associated with your Pikmin Bloom account, you can use your Nintendo Account the next time you log in.

Do not select the Sign-in with Nintendo Account option before linking your existing sign-in method with your Nintendo Account. Doing so may result in errors or inadvertently creating new accounts.
