		/// instead the login operation succeeds and finds an existing user because the association
		/// already exists. Because the user cannot have two product users simultaneously to play with,
		/// the game should prompt the user to choose which profile to keep and which one to discard
		/// permanently. Based on the user choice, the game may then proceed to transfer the Device ID
		/// login into the keychain that is persistent and backed by real user accounts, and if the user
		/// chooses so, move the product user as well into the destination keychain and overwrite the
		/// existing previous product user with it. To clarify, moving the product user with the Device ID

		/// thus automatically login the user to their locally persisted Device ID account.
