<p>New providers and features are being added regularly! See the <a href="https://wordpress.org/plugins/wp-oauth/changelog/" rel="ugc">Changelog</a> for details.</p>
<p>As a reminder, WP-OAuth is a still a pre-v1.0 release, which means some features may not work as intended or might change over time. Please report any bugs/issues to the support forum so they can be fixed as soon as possible. Thank you!</p>
<h4>Facts</h4>
<ul>
<li>With so many sites offering membership now, users may suffer registration fatigue and forget their passwords, or use the same password for several sites, increasing their security risk.</li>
<li><a href="http://www1.janrain.com/rs/janrain/images/Industry-Research-Value-of-Social-Login-2013.pdf" rel="nofollow ugc">56% of consumers</a> have at least one major social network profile they could be using for membership, registration and login purposes across multiple websites without having to maintain multiple accounts and passwords (2013).</li>
<li><a href="http://www.marketingprofs.com/charts/2012/7060/social-media-users-prefer-social-login-over-traditional" rel="nofollow ugc">40% of consumers</a> currently utilize social login (2012).</li>
</ul>
<h4>Features</h4>
<ul>
<li>Free, unlimited, unbranded and white-labeled from the beginning. No upselling, no payment plans, no SaaS, no proxy authentication! WP-OAuth communicates from your WordPress site <em>directly</em> with the <em>trusted</em> third-party login providers.</li>
<li>WP-OAuth collects and stores ONLY the user’s <em>OAuth identity</em> in the WordPress database for future logins; no other user information is collected or stored.</li>
<li>Fully integrates with WordPress. Drops into existing WordPress sites and integrates with existing WordPress users.</li>
<li>Supports third-party authentication with Google, Facebook, LinkedIn, Github, Reddit, Windows Live, PayPal and Instagram via OAuth 2.0 / OpenID Connect. Providers can be enabled or disabled.</li>
<li>Automatic user registration if <em>Anyone can register</em> has been enabled under Settings > General > Membership.</li>
<li>Users can manage their third-party login providers via the standard “Your Profile” WordPress page. They may link more providers, or unlink existing providers.</li>
<li>Displays a message via Javascript to the user when they login or logout. This feature can also be disabled.</li>
<li>Add a custom login form to any post or page using the [wpoa_login_form] shortcode. Choose from 4 different layouts. See <a href="https://wordpress.org/plugins/wp-oauth/installation/" rel="ugc">Installation</a> for details.</li>
<li>Customize the default login screen with a logo or background. Point the logo URL to your home page instead of WordPress.org. Hide the default username/password login form if you want. Automatically include login buttons for any providers that are enabled.</li>
<li>Supports cURL or stream context for the authentication flow, meaning the plugin should be compatible with a wide range of PHP servers.</li>
<li>The authentication flow was adapted from code samples provided by Google, Facebook and LinkedIn. It has been updated, rigorously tested and debugged for solid error handling. Provider implementations share much of the same code (very high code re-use) and the differences between the providers have been fully documented.</li>
<li>The user experience and on-boarding process was inspired by StackExchange/StackOverflow login system.</li>
<li>Extremely light-weight, optimized code base for high performance. Doesn’t require third-party OAuth libraries; everything is built first-class into the plugin. Previously, WP-OpenLogin required LightOpenID and Facebook-PHP-SDK, but this is no longer necessary. Keeps the bloat low and the performance high. Tested with P3 Plugin Profiler, WP-OAuth’s plugin overhead is around 0.001 seconds which is 6x less overhead than Akismet in the same run! That means there shouldn’t be a performance hit.</li>
</ul>

<h3>History</h3>
<p>This project is a continuation of <a href="http://github.com/perrybutler/wp-openlogin" rel="nofollow ugc">WP-OpenLogin</a> which was originally developed with OpenID in mind. We’re moving on; OAuth 2.0 is now the standard.</p>


WP-OAuth

<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>

</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>
