takeOverTypeModelsList<TakeOverTypeModel>~ 1000 itemsTakeover Type Model
This model defines Takeover Information.

Takeover Information is used when changing devices or moving/sharing an account across platforms.
It consists of a unique string that identifies an individual and a password; by entering the correct combination, an Account (GS2 anonymous account) can be retrieved.

Multiple sets of Takeover Information can be configured for a single Account.
To configure multiple sets, you must assign each one to a different slot.
Slots can be specified from 0 to 1024, allowing for up to 1,025 types of Takeover Information to be set.

A typical example would be to store the account information for “Sign in with Apple” in slot 0 and the information for a Google account in slot 1.
It should be noted that this Takeover Information serves only as a data holder; the authentication mechanism for social accounts must be prepared separately.
