The author info box is a small section that displays information about the post author including links to their website and social profiles. In post, we will put into words how to add author info box in WordPress.
Adding author info box in WordPress posts have two different methods but with this post we will only feature one method. This method is using plugin which is the Guerrilla’s Author Box. You need to install and activate the plugin. Each author on your site will need to add their biographical information and links to their user profiles by logging in to their WordPress account on your website and click on the Profile link from the WordPress admin menu. As a site administrator, you must visit Users > All User page, and click on the link below the user profile you want to edit. By visiting any WordPress post on your site, you will see the author info box below the post.
If you go with the second method where you can display the author info in a sidebar widget, kindly check this article.
