Login Process

  1. Authentication Service (Kakao) Login

    1. The Kakao Game SDK executes IDP authentication and verifies the authentication result on the platform server, then returns the result.

    2. Authentication details such as the “Player ID” and “Authentication Token” can be obtained.

  2. Game Server Authentication

    1. The “Player ID” and Authentication Token (ZAT) are sent to the game server to verify the platform authentication details.

    2. This process is required to check the validity of the game client connected to the game server if a game server exists.
