Please check Privacy Portal’s <a href="https://privacyportal.org/privacy" rel="nofollow ugc">Privacy Policy</a> and <a href="https://privacyportal.org/tos" rel="nofollow ugc">Terms Of Service</a> for more information.
<h3>Sign In With Privacy Portal</h3>
<a href="https://privacyportal.org" rel="nofollow ugc">Privacy Portal</a> is an OAuth 2.0 Provider with Privacy baked-in. When Sign In With Privacy Portal 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.
<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>
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.
<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>

Authorizer restricts access to a WordPress site to specific users, typically students enrolled in a university course. It maintains a list of approved users that you can edit to determine who has access. It also replaces the default WordPress login/authorization system with one relying on an external server, such as Google, CAS, LDAP, or an OAuth2 provider. Finally, Authorizer lets you limit invalid login attempts to prevent bots from compromising your users’ accounts.
View or contribute to the plugin source on GitHub: <a href="https://github.com/uhm-coe/authorizer" rel="nofollow ugc">https://github.com/uhm-coe/authorizer</a>
Authorizer requires the following:
<ul>
<li>CAS server (2.x, 3.x, 4.x, 5.x, 6.x, or 7.x) or LDAP server (plugin needs the URL)</li>
<li>PHP extensions: php-ldap, php-curl, php-dom</li>
</ul>
Authorizer provides the following options:
<ul>
<li>Authentication: WordPress accounts; Google accounts; CAS accounts; LDAP accounts; OAuth2 accounts</li>
<li>Login Access: All authenticated users (all local and all external can log in); Only specific users (all local and approved external users can log in)</li>
<li>View Access: Everyone (open access); Only logged in users</li>
<li>Limit Login Attempts: Progressively increase the amount of time required between invalid login attempts.</li>
<li>Shortcode: Use the <code>[authorizer_login_form]</code> shortcode to embed a wp_login_form() outside of wp-login.php.</li>
</ul>

Authorizer

Integrates nicely with Google hosted domain/s. Couldn't be happier with how it works!

Integrates well with Google Logins

I've experimented this plugin on a multisite and everything works pretty well.

Works great even on a multisite setup

Authorizer limits login attempts, restricts access to specific users, and authenticates against external sources (OAuth2, Google, LDAP, or CAS).
