By default, WordPress arrives with five default user roles: Contributor, Subscriber, Author, Editor, and Administrator.
However, when you start installing plugins, you may see many extra roles.
For example, if you install Yoast SEO, there will be two new roles: “SEO Editor” and “SEO Manager”. If you then add WooCommerce, you’ll find two more roles: “Shop manager” and “Customer”. The more plugins you add, the longer this list will become.
