Description

The BACKND SDK provides a feature to change an account registered via federation to another federation account.\ After a user who signed up via federation logs in, they can call the ChangeToFederation method to switch to a different federation account.\ After switching, the user can log in with the newly linked federation account and continue using their existing game data.\ If the user logs in again with their previous custom or federation account, a new account will be created.\ For more information on federationToken and type required for the ChangeToFederation method, please refer to the Federation authentication documentation.
