Co-Authors Plus for WordPress

Assign multiple bylines to posts, pages, and custom post types via a search-as-you-type input box. Co-authored posts appear on a co-author’s archive page and in their feed. Co-authors may edit the posts they are associated with, and co-authors who are contributors may only edit posts if they have not been published (as is core behavior).

Add writers as bylines without creating WordPress user accounts. Simply create a guest author profile for the writer and assign the byline as you normally would.

On the frontend, use the Co-Authors Plus template tags or the block editor blocks to list co-authors anywhere you’d normally list the author.

Upgrading to 4.0

Co-Authors Plus is an almost complete rewrite of the Co-Authors plugin originally developed by Weston Ruter (2007). The original plugin was inspired by the ‘Multiple Authors‘ plugin by Mark Jaquith (2005).
