<p>The Access Expiration plugin is a plugin from Multinc that adds a level of access control for particularly sensitive posts.  For each post or category, you can limit the number of views and the amount of time that an item remains viewable by each user after he or she first accesses the post.  Unlike other plugins that expire posts for all users at the same time, this plugin keeps track of every user?s viewing history so that each gets equal access time.</p>
<p>You can also impose separate limits for unregistered users, who are all considered as one single user.</p>
<p>When used in combination with the other plugins in the <a href="https://wordpress.org/extend/plugins/social-privacy/">Social Privacy</a> set, this plugin is useful for limiting the chance that any authorized user accidentally or deliberately forwards a private post to an unauthorized user.</p>
<p>Because authorized users may have legitimate reasons for accessing a post beyond the allotted time, the plugin gives users the simple option of requesting an extension of their viewing privileges.</p>

<p>Social Privacy is a set of open-source plugins for WordPress that restrict the read access of posts or categories to only specified registered users. Install these plugins and you can start blogging for friends and family about topics that are too sensitive to publish publicly.</p>
<p>Some social networks like Facebook support user blogs with extensive privacy control.  Social Privacy grants bloggers an even greater level of privacy control, outside of these walled gardens — right here in the blogosphere.</p>
<h4>Summary of Features</h4>
<p>Which posts can be restricted?</p>
<ul>
<li>individual posts</li>
<li>categories of posts (multiple categories are supported)</li>
</ul>
<p>To whom can posts be restricted?</p>
<ul>
<li>all registered users</li>
<li>specific registered users</li>
</ul>
<p>Which access method is controlled?</p>
<ul>
<li>web site</li>
<li>syndicated news feed (RSS or ATOM)</li>
<li>email</li>
</ul>
<p>For protected posts, what will users see in their syndicated feeds?</p>
<ul>
<li>authorized users will see either the full post or a summary (with a link to the full post on the web)</li>
<li>unauthorized users will see only a title or not even see that there is a new post</li>
</ul>
<p>For public posts or for protected posts, what email content can be sent to authorized users?</p>
<ul>
<li>full post</li>
<li>excerpt (with a link to the full post on the web)</li>
<li>title only (with a link to the full post on the web)</li>
<li>no email</li>
</ul>
<p>Security usually increases inconvenience for users.  What convenience features are supported to balance the additional security?</p>
<ul>
<li>automatic user recognition and authentication when the user clicks in the syndicated feeds to go the blog post on the website</li>
<li>the same for emails</li>
</ul>
<h4>Advanced Features</h4>
<p>How can one minimize the chance that unauthorized users be able to read protected posts forwarded to them by authorized users?</p>
<ul>
<li>a warning message can be included in every web page, feed item, or email for protected posts discouraging permitted users from forwarding</li>
<li>feed items and email notifications can include limited content, forcing authorized users to go to the web to read the full post, which is less trivial to forward</li>
<li>authorized users can be forced to enter their full login and password when reading the full post on the web, by disabling the automatic user recognition feature</li>
<li>the number of times that any specific user can view a post or certain categories of posts can be limited.  Setting this to “1 maximum view” while enabling the automatic user recognition feature can provide a particularly good balance of security vs. convenience</li>
<li>similarly to the above, the amount of time that any specific user can view a post or certain categories of posts again can also be limited</li>
</ul>
<h4>Sub-plugins in the Set</h4>
<p>The following 5 plugins have been created or modified to work in unison to give you complete control over access to the posts in your WordPress installation.  If installed individually, some of these plugins provide significant functionality on their own, but their best features are enabled when installed as one set.</p>
<h3>[Social Access Control](https://wordpress.org/extend/plugins/social-access-control/) (based on [Category Access](http://www.coppit.org/blog/archives/173))</h3>
<p>Based on the 3rd-party Category Access, this plugin provides the core functionality for restricting the access permissions of posts.  This gives you the ability to permit only specific registered users to read certain posts or certain categories of posts.</p>
<h3>[Subscribe2 for Social Privacy](https://wordpress.org/extend/plugins/subscribe2-for-social-privacy/) (based on [Subscribe2](https://wordpress.org/extend/plugins/subscribe2/))</h3>
<p>Based on the 3rd-party Subscribe2, this plugin allows registered and unregistered users to be notified via email whenever there is a new post that they are permitted to access.  Users can choose between different email contents and post categories.</p>
<h3>[Private Files for Social Privacy](https://wordpress.org/extend/plugins/private-files-for-social-privacy/) (based on [Private Files](https://wordpress.org/extend/plugins/private-files/))</h3>
<p>The 3rd-party Private Files plugin tightens the security of private posts by preventing clever users from obtaining unauthorized access to contained images and other attachments.</p>
<p>Private Files was enhanced to respect the access permissions of the Social Access Control plugin.</p>
<h3>[Unique URL Authentication](https://wordpress.org/extend/plugins/unique-url-authentication/)</h3>
<p>The Unique URL Authentication plugin is a new plugin from Multinc that works with the Social Access Control plugin to add access control to syndicated feeds.  Since popular web feed readers such as Google Reader do not support private feeds that require a login and a password, a common solution is to give each registered user their own unique and unguessable feed URL.  With this plugin installed, each user will have his or her own feed and will receive a listing of only the feed items that he or she has access to.</p>
<p>Also, the links contained in each feed item and each email notification that point back to the blog website can also benefit from password-less authentication.  This allows sensitive posts to remain on the website rather than sent out, while giving authorized users single-click convenience.</p>
<h3>[Access Expiration](https://wordpress.org/extend/plugins/access-expiration/)</h3>
<p>The Access Expiration plugin is another new plugin from Multinc that adds another level of access control for particularly sensitive posts.  For each post or category, you can limit the number of views and the amount of time that an item remains viewable by each user after he or she first accesses the post.  Unlike other plugins that expire posts for all users at the same time, this plugin keeps track of every user’s viewing history so that each gets equal access time.  This plugin is useful for limiting the chance that any authorized user accidentally or deliberately forwards a private post to an unauthorized user.</p>
<p>Because authorized users may have legitimate reasons for accessing a post beyond the allotted time, the plugin gives users the simple option of requesting an extension of their viewing privileges.</p>
