The LINE Platform offers a system to integrate desktop and mobile websites with LINE. This section explains how to integrate your website with LINE.

Login types

The LINE Platform provides several ways to log in with a LINE account:

  • Log in with the LINE app for smartphone apps
  • Log in on any desktop or mobile website

The LINE Platform gives you the ability to use LINE Login for both smartphone apps and websites.

Login for smartphone apps

Android and iOS apps can delegate the task of authenticating users to the LINE app installed on the device. Users do not need to enter their email address and password because they are already logged in to LINE. This is a big benefit for users.

You can use the LINE SDK for Android or iOS to apply this login feature. See the following pages for more information:
