About Invalidate Logged Out Cookies
From the official readme · v0.1.1Description
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.
Installation
- Upload the entire
invalidate-logged-out-cookies/directory to the/wp-content/plugins/directory - Activate the plugin through the ‘Plugins’ menu in WordPress
- If upgrading manually, make sure to disable and then re-enable the plugin (upgrading through the admin interface will do this automatically)
