<li>Restricting access to authorized users by requiring a password for access</li>
<li>Removing descriptions and excerpts from the feed</li>
<li>Removing author names from the feed</li>
</ol>
RSS is a type of web feed that allows your readers to automatically get new content in email newsletters and RSS feed readers.
RSS feeds can be useful for your website when running a blog but are unnecessary if using WordPress as a basic website builder or ecommerce site. Some blog posts may also be gated content and be intended to be visible by authorized users only.
