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. Works logged in or out as a WordPress user. Uses the same functionality WordPress uses to set post cookies. Has a simple settings page to make everything easier. Allows you to alert user they have logged out.
