WordPress comes right out of the box with unlimited numbers of users and 5 user roles (permissions, essentially). To access, view or add users, go to Users >> All Users.
Summary of capabilities for each of the 5 user roles:
- Administrator – can access to all the administration features within a single site.
- Editor – can publish and manage posts including the posts of other users.
- Author – can publish and manage their own posts.
- Contributor – can write and manage their own posts but cannot publish them.
- Subscriber – can only manage their profile info and password.
Security Note: Use the Administrator role sparingly. It’s really only for users that actually need to edit, update and otherwise admin the site. If an Admin user’s account was hacked or compromised, it puts the whole site in jeopardy.
With some plugins, additional user roles can be created and even edited. More on that later.
