<p>The OAuth plugin for WordPress allows you to provide authentication against any<br />
OAuth provider. This plugin is uses the OAuth library by Manuel Lemos. The<br />
plugin allows the admin to select any from the services supported<br />
out-of-the-box by the said library. Additionally it is possible to configure a<br />
service manually, which means any site supporting the OAuth protocol can<br />
be used.</p>

<h3>Sign In With Privacy Portal</h3>
<p><a href="https://privacyportal.org" rel="nofollow ugc">Privacy Portal</a> is an OAuth 2.0 Provider with Privacy baked-in. When <em>Sign In With Privacy Portal</em> is enabled, users can log in to your site while preserving their privacy using the Privacy Portal OAuth provider. During the login process, <a href="https://privacyportal.org" rel="nofollow ugc">Privacy Portal</a> protects user privacy by generating email aliases (also known as Privacy Aliases) that relay emails to users’ personal email addresses, keeping them private.</p>
<ol>
<li>The “Sign In With Privacy Portal” button will be displayed on your site. (It can be added to any page.)</li>
<li>Visitors to your site can click on the button to initiate the login process.</li>
<li>Once clicked, they will be redirected to the Privacy Portal web app to authorize access to your site.</li>
<li>After authorization, users will be redirected back to your site. Existing users will be automatically logged into WordPress, while new users will be created in the WordPress database and then logged in.</li>
</ol>
<h3>Subscribe Anonymously With Privacy Portal</h3>
<p>When “Subscribe Anonymously with Privacy Portal” is enabled, users can subscribe to your existing newsletter using email aliases instead of their personal email addresses. This feature does not replace your existing newsletter setup; instead, it integrates with some popular newsletter plugins.</p>
<ol>
<li>The “Subscribe Anonymously” button will be displayed within your newsletter forms. (It can be added to any page.)</li>
<li>Visitors to your site can click on the button to enroll anonymously in your newsletter without having to enter their email address.</li>
<li>Once clicked, they will be redirected to the Privacy Portal web app to authorize access to your site.</li>
<li>After authorization, Privacy Portal generates an email alias that is used to enroll the user in your newsletter. Note that the user remains anonymous throughout the process.</li>
</ol>
<h3>Important Notes</h3>
<ul>
<li>With Privacy Portal SSO, users will be redirected to the Privacy Portal web app, where they need to log in with their Privacy Portal account to authorize access to your site. If they don’t have an account, they can create a free one during this process.</li>
<li>When sending an email to a user’s email alias, your email is delivered to Privacy Portal’s Mail Relay servers, which privately redirect it to the user’s personal email address. Mail Relay does not store emails; it processes them in-memory and can add a layer of encryption when configured by users.</li>
</ul>
