Due to lack of interest (both my own and based on the number of downloads) this plugin will not be updated for WP 3.0
WordPress’ auth cookies include a built-in expiration date (either 2 or 14 days depending on if the ‘Remember Me’ option is checked). Even if you remove the client-side cookie (by manually logging out or just closing your browser if ‘Remember Me’ wasn’t checked when logging in) the data that was stored within the cookie is still valid until the expiration date is reached.
This could be an issue if someone managed to “steal” your cookie(s). They would still be able to access your website for some time into the future.
This plugin will immediately invalidate your auth cookies when you manually log out. This, of course, also means that you have to manually click ‘Log out’ for this plugin to work properly (you can’t just close your browser to remove any cookies that expire at the end of the session). This won’t prevent session hijacking, but should limit the amount of time that an attacker can access your website.

Invalidate Logged Out Cookies

This plugin will immediately invalidate your auth cookies when you manually log out.

There are 3 shortcodes that can be used:
<pre><code>[logout] - A standard Log Out link, where the user stays on the login screen after being logged out.
[logout_to_home] - A link that logs the user out, and redirects them to your home page.
[logout_to_current] - A link that logs the user out, and redirects them back to the current page/URL.
</code></pre>
Advanced Usage:
All 3 shortcodes all support 3 attributes/parameters:
<pre><code>[logout text="" class="" redirect=""]
</code></pre>
The 3 supported attributes/parameters are:
<pre><code>text=""
</code></pre>
– The text to use for the link anchor text. 
– Default: <code>Log Out</code> 
 class=”” 
– The HTML class(es) to use for the link. Multiple classes should be separated by a space. 
– Default: <code>logout</code> 
 redirect=”” 
– The path/URL to redirect the user to after they are logged out. 
– Default: the WordPress login screen. 
– Note: must be a URL or path on the same domain name as the WordPress website (cannot be an external domain/URL)
Some Examples: 
 [logout text=”Log Off”] – A <code>Log Off</code> link that logs the user out. 
 [logout redirect=”/members/”] – Log the user out, and redirect them to <code>/members/</code>. 
 [logout_to_home text=”Log Off”] – A <code>Log Off</code> link that logs the user out and redirects them to your home page. 
 [logout class=”log-out-link”] – Use a custom CSS/HTML class name for the log out link.
Note: the shortcodes will return nothing/empty if the user isn’t logged in.

Easily add a log out link or button to a post or page using a simple shortcode.
