The Custom Guest Authors plugin (developed and maintained by Mohd Elfie Nieshaem Juferi) lets you replace the WordPress post author display name with one or more custom guest author names, stored as post meta. No separate WordPress user accounts are required. Ideal for sites that publish content from external contributors, translators, or collaborative authors.
Guest author names are set directly from the post editor via a dedicated sidebar panel — available in both the classic editor and the Gutenberg block editor. The raw guest-author custom field key also works for programmatic or WP-CLI workflows.
This plugin was inspired by a tutorial from WPBeginner.
