LINE Login v2.1 Reference & Development Guide
Overview
LINE Login v2.1 is a social authentication and authorization service based on the OAuth 2.0 Authorization Code Grant flow and OpenID Connect 1.0 specifications. Integrating LINE Login into web apps or native mobile/desktop apps enables seamless registration, single sign-on (SSO), profile retrieval, and secure user identification using LINE accounts.
When to Use
- Implementing user login and registration via LINE accounts on web or mobile applications.
- Making OAuth 2.0 authorization requests (
https://access.line.me/oauth2/v2.1/authorize). - Exchanging authorization codes for access tokens and OpenID Connect ID Tokens (
https://api.line.me/oauth2/v2.1/token). - Verifying ID tokens or Access Tokens on backend services to authenticate users securely.
- Retrieving user profile details (User ID, Display Name, Picture URL, Status Message) or email addresses.
- Managing access tokens (verification, refreshing, revoking).
- Implementing PKCE (Proof Key for Code Exchange) or configuring two-factor authentication (2FA).
