This plugin adds optional per-page user name and password protection, implemented using standard HTTP protocol authorization headers, thus triggering the standard user/password dialog of the browser, and making it possible to make the browser store the credentials.
Subpages of a protected page are protected with the same user name and password as their parent.
Protected pages and their subpages do not show up in menus, search results and page lists.
<h4>Usage</h4>
<ol>
<li>When editing a page, locate the section titled “Page Protection” (probably located near the bottom of the right sidebar).</li>
<li>Check the box “Protect page and subpages”, and provide a user name and password combination.</li>
<li>Optionally, check the box “Make page and subpages searchable”, if you want the page and its subpages turn up in search results, but only with their title, not their content.</li>
<li>Save your page.</li>
</ol>
