Tap into LINE's network of users by integrating LINE Login into your Auth0 apps. Give users an easier way of logging in and increase your conversion rates. LINE is a messaging platform offering free one-on-one and group texts to for friends anytime, anywhere. LINE also provides unlimited voice and video calls free for users. LINE connects millions of people around the world every day.

<p>The LINE social connection allows users to log in to your application using their LINE profile.</p>
<p>By default, Auth0 automatically syncs user profile data with each user login, thereby ensuring that changes made in the connection source are automatically updated in Auth0. Optionally, you can <a href="https://auth0.com/docs/users/configure-connection-sync-with-auth0">disable user profile data synchronization</a> to allow for updating profile attributes from your application.</p>


<h2 id="prerequisites">Prerequisites</h2>
<p>Before you begin:</p>
<ul>
<li>  <a href="https://www.linebiz.com/jp-en/other/">Sign up for a LINE account</a>.</li>
<li>  Register your LINE account as a Developer. If you&#39;ve never logged in to the <a href="https://developers.line.biz/console/">LINE Developer console</a> before, do so; you&#39;ll automatically be asked to register as a developer and link your account.</li>
</ul>


<h2 id="set-up-channel-in-line">Set up channel in LINE</h2>
<p>Set up a provider and channel using LINE&#39;s <a href="https://developers.line.biz/en/docs/liff/getting-started/">Create a Channel</a> documentation, then apply for email permissions using LINE&#39;S <a href="https://developers.line.biz/en/docs/line-login/integrate-line-login/#applying-for-email-permission">Integrating LINE Login with your web app: Applying for email permission</a> section. During this process, LINE will generate a <strong>Channel ID</strong> and <strong>Channel Secret</strong> for your application; make note of these.</p>

<table class="table"><thead><tr><th>Field</th><th>Value to Provide</th></tr></thead><tbody><tr><td>Application type</td><td>Enable <strong>Web app</strong>.</td></tr><tr><td>Callback URL</td><td><code>https://YOUR_DOMAIN/login/callback</code></td></tr></tbody></table>

<h3 id="find-your-auth0-domain-name">Find your Auth0 domain name</h3>

For example, if your tenant name were <code>exampleco-enterprises</code>, your Auth0 domain name would be <code>exampleco-enterprises.us.auth0.com</code> and your callback URL would be <code>https://exampleco-enterprises.us.auth0.com/login/callback</code>. (If your tenant is in the US and was created before June 2020, then your domain name would be <code>https://exampleco-enterprises.auth0.com</code>.)</p>
