A benefit to WordPress is the ability to create multiple users and assign them permissions. Maybe you want to create another administrator to your website or you want to add contributors to your site but don’t want to give them any admin access.
1. To create a user look for the Users section of the sidebar in the WordPress admin panel and click on Add New.
2. Simply fill out the fields, hit submit, and your user is created.
