When creating a WordPress syndication channel, you will be asked for a username and password. If the content on your WordPress site is locked to the public, you may need this information (with wp-json permission), but if your site is publicly available, you can leave these fields blank.

Once created, the WordPress channel can be searched and browsed like any other channel. When it is desirable to import a content item, an administrator can click and import a single item.

Or, an "automatic importer" can be created which will ingest content on a schedule.
