This feature is supported in the Windows environment. If you do not use the default login UI provided by the SDK and instead implement your own login UI, the SDK offers a feature to set up auto login. If you do not configure auto login, the SDK will not create a file for automatic login by default. The file for auto login is created and stored in an encrypted format in the folder "C:\Users\[User]\AppData\Local\.kakaogames\[AppdID]" under the name ".access". This is because multiple users can exist on a single PC." When a game is uninstalled and then reinstalled, if the auto login file remains, the SDK checks whether an encrypted ".access" file exists in the location of the Windows SDK file (KakaoGame.dll). If the file is valid, the SDK loads the file containing the auto login information and performs the auto login. If the auto login files are corrupted, the SDK will delete them. If the auto login file exists and the user logs out or withdraws, the auto login file will be deleted.
