PublishPress Authors is the best plugin for adding many authors to one WordPress post. You can create multiple authors, co-authors and guest authors.
MULTIPLE AUTHORS AND CO-AUTHORS
With PublishPress Authors, you can set multiple authors and coauthors for each post. When you write a post, you’ll see a box in the right sidebar. Here you can choose from all the users on your site, and assign them as authors.
On the frontend of your site, PublishPress Authors gives you several different options to display the authors’ box:
- Replacing the default author display.
- At the bottom of your content.
- In a widget or a Gutenberg block.
- Using shortcodes.
- Adding filters and actions in your template files.
