This plugin allows you to set expiry dates for user logins. You can set a user to:
<ul>
<li>Never expire (default)</li>
<li>Expire in X days, weeks, moths or years</li>
<li>Expire on a specific date</li>
</ul>
When a user expires you can:
<ul>
<li>Change the role of that user</li>
<li>Replace the user’s password with a randomly generated one</li>
<li>Send an email notification to the user</li>
<li>Send an email notification to the site administrator</li>
<li>Remove expiry details and allow user to continue to login</li>
<li>Perform you own actions using an <a href="https://github.com/benhuson/expire-users/wiki/expire_users_expired" rel="nofollow ugc"><code>expire_users_expired</code></a> hook</li>
</ul>
You can automatically assign expiry details to users who sign up via the register form.
The email notification messages can be configured in the admin settings.

Expire Users

Seth Yoder

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.

Password Protection Expiration

Allows you to easily change the lifetime of the WordPress cookie which allows automatic login to password-protected posts.
