# LINE SDK for Unity overview
The LINE SDK for Unity provides a modern way of implementing LINE APIs. The features included in this SDK will help you develop a Unity game with engaging and personalized user experience.
# User authentication
This feature allows users to log in to your Unity game with their LINE accounts. With the help of the LINE SDK for Unity, it has never been easier to integrate LINE Login into your app. Your users will automatically log in to your app without entering their LINE credentials if they are already logged in to LINE on their Android devices. This offers a great way for users to get started with your app without having to go through a registration process.
# Utilizing user data with OpenID support
Once the user is authorized, you can get their LINE profile. You can make use of the user's information registered in LINE without building your own user system.
The LINE SDK supports the OpenID Connect 1.0 specification. You can get ID tokens that contain the user’s LINE profile when you retrieve the access token.
# API calls
Use the methods included in the LINE SDK to get user profile information, log out users, and manage access tokens.
