<p>There is no built-in way for your visitors to “log out” of password protected posts once they’ve entered the password. Even logged in users cannot log out of password protected posts by logging out of their account. This plugin solves that problem by providing a link for your visitors to log out of password protected posts.</p>
<h3>Setup</h3>
<p>After installing the plugin, add the following code somewhere in your theme to display a link for logging out of password protected posts:</p>
<pre><code><?php do_action( 'posts_logout_link' ); ?>
</code></pre>


Log Out Password Protected Posts

Provides a template tag for a link for visitors to log out of password protected posts.

<p>This plugin simply adds a logout button to the content of any password protected post. Sometimes clients want a password protected page to share information with privileged individuals and the default 10 days for the cookie to expire is too long for their liking. So I wrote a little plugin to do this with AJAX and set the cookie to expire immediately, well actually 10 days in the past.</p>
<ul>
<li>Works logged in or out as a WordPress user.</li>
<li>Uses the same functionality WordPress uses to set post cookies.</li>
<li>Has a simple settings page to make everything easier.</li>
<li>Allows you to alert user they have logged out.</li>
</ul>
