PlayFab でログイン

Signs the user into the PlayFab account, returning a session identifier that can subsequently be used for API calls which require an authenticated user. Unlike most other login API calls, LoginWithPlayFab does not permit the creation of new accounts via the CreateAccountFlag. Username/Password credentials may be used to create accounts via RegisterPlayFabUser, or added to existing accounts using AddUsernamePassword.
