When you password-protect a post in WordPress, a cookie is set to expire in 10 
days which prevents the user from having to enter the password during that 
10-day period. This plugin allows you to easily change the lifetime of that 
cookie.

A simple plugin that allows you to set an expiration date on posts. Once a post is expired, “Expired” will be prefixed to the post title.
You can show the expiration status of a post using the [expires] short code.
The [expires] short code accepts 5 optional parameters:
<ul>
<li>
expires_on – The text to be shown when a post has not yet expired. Default: <code>This item expires on: %s</code>
</li>
<li>
expired – The text to be shown when a post is expired. Default: <code>This item expired on: %s</code>
</li>
<li>
date_format – The format the expiration date should be displayed in
</li>
<li>
class – The class or classes given to the DIV element
</li>
<li>
id – The ID given to the DIV element
</li>
</ul>
The <code>%s</code> will be replaced with the expiration date.
