Co-Authors Plus is an old and popular WordPress plugin.

By default, WordPress allows you to choose a single author for content. Co-Authors Plus was a solution to this, because it allowed you to assign multiple authors to one content item.

However, Co-Authors Plus has only had a small number of updates in the last few years. Also, it can be hard to use because it requires you to edit your template files.

The PublishPress Authors plugin is a major update of Co-Authors Plus that's worth checking out.

We reviewed the main PublishPress plugin, which is a really good editorial calendar. PublishPress Authors is an extra plugin from the same team.

Guide to PublishPress Authors

If you install PublishPress Authors, you'll see a new box on the right-hand side of all your posts. You can add and remove authors on this screen (click here to learn about Authors permissions in WordPress).

Instead of manually editing your template files, the Multiple Authors add-on gives you several different options to display the authors’ box:

  1. At the bottom of your content
  2. In a widget
  3. Via a shortcode
  4. Replacing the default author dispaly

And yes, if you want to do things manually, there are filters and actions available so you can add the Multiple Authors output to your template files.

However, the widget is probably the easiest and most flexible solution. Here's how the Multiple Authors plugin appears on the frontend of a site, inside a widget:

Here's how Multiple Authors can automatically replace the core author display:

The "Multiple Authors" feature doesn’t appear on all post types by default. You need to select what post types you want to use:

You can also configure several different layout options for the content.

All-in-all, "PublishPress Authors" is a worthy successor to the older Co-Authors Plus plugin and has some nice extra features that make it easier to use.
