<p>Ultra minimal plugin to let your users login to WordPress applications using their Google accounts. No more remembering hefty passwords!</p>
<h3>Initial Setup</h3>
<ol>
<li>
<p>Create a project from <a href="https://console.developers.google.com/apis/dashboard" rel="nofollow ugc">Google Developers Console</a> if none exists.</p>
</li>
<li>
<p>Go to <strong>Credentials</strong> tab, then create credential for OAuth client.</p>
<ul>
<li>Application type will be <strong>Web Application</strong></li>
<li>Add <code>YOUR_DOMAIN/wp-login.php</code> in <strong>Authorized redirect URIs</strong></li>
</ul>
</li>
<li>
<p>This will give you <strong>Client ID</strong> and <strong>Secret key</strong>.</p>
</li>
<li>
<p>Input these values either in <code>WP Admin > Settings > WP Google Login</code>, or in <code>wp-config.php</code> using the following code snippet:</p>
<p><code>define( 'WP_GOOGLE_LOGIN_CLIENT_ID', 'YOUR_GOOGLE_CLIENT_ID' );<br />
define( 'WP_GOOGLE_LOGIN_SECRET', 'YOUR_SECRET_KEY' );</code></p>
</li>
</ol>
<h3>Browser support</h3>
<p><a href="https://developers.google.com/identity/gsi/web/guides/supported-browsers" rel="nofollow ugc">These browsers are supported</a>. Note, for example, that One Tap Login is not supported in Safari.</p>
<h3>How to enable automatic user registration</h3>
<p>You can enable user registration either by<br />
– Enabling <em>Settings > WP Google Login > Enable Google Login Registration</em></p>
<p>OR</p>
<ul>
<li>Adding<br />
<code>define( 'WP_GOOGLE_LOGIN_USER_REGISTRATION', 'true' );</code><br />
in wp-config.php file.</li>
</ul>
<p><strong>Note:</strong> If the checkbox is ON then, it will register valid Google users even when WordPress default setting, under</p>
<p><em>Settings > General Settings > Membership > Anyone can register</em> checkbox</p>
<p>is OFF.</p>
<h3>Restrict user registration to one or more domain(s)</h3>
<p>By default, when you enable user registration via constant <code>WP_GOOGLE_LOGIN_USER_REGISTRATION</code> or enable <em>Settings > WP Google Login > Enable Google Login Registration</em>, it will create a user for any Google login (including gmail.com users). If you are planning to use this plugin on a private, internal site, then you may like to restrict user registration to users under a single Google Suite organization. This configuration variable does that.</p>
<p>Add your domain name, without any schema prefix and <code>www,</code> as the value of <code>WP_GOOGLE_LOGIN_WHITELIST_DOMAINS</code> constant or in the settings <code>Settings > WP Google Login > Whitelisted Domains</code>. You can whitelist multiple domains. Please separate domains with commas. See the below example to know how to do it via constants:<br />
    <code>define( 'WP_GOOGLE_LOGIN_WHITELIST_DOMAINS', 'example.com,sample.com' );</code></p>
<p><strong>Note:</strong> If a user already exists, they <strong>will be allowed to login with Google</strong> regardless of whether their domain is whitelisted or not. Whitelisting will only prevent users from <strong>registering</strong> with email addresses from non-whitelisted domains.</p>
<h3>Hooks</h3>
<p>For a list of all hooks please refer to <a href="https://github.com/rtCamp/login-with-google#hooks" rel="nofollow ugc">this documentation</a>.</p>
<h4>wp-config.php parameters list</h4>
<ul>
<li>
<p><code>WP_GOOGLE_LOGIN_CLIENT_ID</code> (string): Google client ID of your application.</p>
</li>
<li>
<p><code>WP_GOOGLE_LOGIN_SECRET</code> (string): Secret key of your application</p>
</li>
<li>
<p><code>WP_GOOGLE_LOGIN_USER_REGISTRATION</code> (boolean) (optional): Set <code>true</code> If you want to enable new user registration. By default, user registration defers to <code>Settings > General Settings > Membership</code> if constant is not set.</p>
</li>
<li>
<p><code>WP_GOOGLE_LOGIN_WHITELIST_DOMAINS</code> (string) (optional): Domain names, if you want to restrict login with your custom domain. By default, it will allow all domains. You can whitelist multiple domains.</p>
</li>
</ul>
