Post Lockdown is a free WordPress plugin designed to enhance the security of your website's critical pages and posts. It prevents non-admin users from trashing or deleting important content, ensuring that essential information remains intact. The plugin allows users to lock pages and posts, disabling editing capabilities alongside the trashing and deletion features. This is particularly useful for maintaining the integrity of content that should not be altered or removed by non-administrative personnel.

The user interface is straightforward, featuring an options page accessible from the Settings menu within the WordPress admin panel. Users can easily search for and select pages and posts of any post type to lock or protect. Once selected, a simple click allows users to move items into a designated box for protection, followed by a quick Save Changes action. This functionality ensures that editors can view which posts are locked, providing clarity in content management.
