This plug-in adds a meta box to the post and page writing pages in wp-admin to set up an expiration date for that item. It uses the WordPress cron feature to be executed once a day.
After the expiration date the post will be in the trash can of WordPress. The plug-in does not delete any post, but WordPress will depending on the trash can settings.

Do you use the “Remember Me” feature when logging in to your WordPress site? I know I do.
Do you find it annoying when WordPress stops remembering you after a few days? I know I do.
Longer Login is a simple WordPress plugin that remedies this. By default, WordPress automatically 
forgets users after 14 days. This plugin adds an option in your website’s General Settings that 
can change this expiration date. There are numerous options ranging from 1 day to 1 year.
Change the setting, and the next time you, or any user on your site logs in with “Remember Me” checked, 
WordPress will keep them logged in for that specified time.
<h4>How Does It Work?</h4>
To remember users, websites store a small piece of information in your web browser’s memory. 
This token of information is called an <a href="wikipedia.org/wiki/HTTP_cookie" rel="nofollow ugc">HTTP cookie</a>. These 
cookies have an expiration date specified by the website.
By default, WordPress websites have their persistent login cookies expire after 14 days. This plugin 
changes the length of time the cookie will survive. Instead of 14 days after login, you can make the 
cookie live for as long as 1 year after login.
