LINE Login lets people easily create an account for your app or website using their LINE accounts. You can integrate LINE Login into your iOS, Android, or web app.

Get started with LINE Login


Integrate LINE Login into your website to make it easier for people to create an account and log in. With LINE Login, your users can automatically log in to your website if they are already logged in to LINE on their device. The authentication and authorization process is based on the OAuth 2.0 and OpenIDĀ® Connect protocols. For more information, see Integrating LINE Login.

For an example of how LINE Login can provide users with an improved experience, see the LINE STORE website.
