It might happen that multiple authors work on a single blog post, especially when you are collaborating with co-authors on a lengthy, research-based article. On various content management systems this facility is already there, but in WordPress, it is not inbuilt. For instance, you cannot assign multiple authors to a single blog post or a single page. You need a plug-in, and one of such plug-ins is Co-Authors. Once you can assign multiple authors to a single WordPress blog post, it is a matter of inserting a small code in your theme file to show the list of associated authors to the public.

The extra authors drop-down menus are prefilled with the existing contributors and authors so you need to simply select them. You can easily remove them by clicking the x button.

Once you have made these changes, you are all set to go.
