If you want to limit what certain members of your web team can and can’t do when they log into your WordPress Dashboard, you, as the Administrator of the WordPress website, can assign one of five different “roles” to any individual:
The Administrator’s Role
The highest level of responsibility for a single WordPress website* is assigned to the Administrator(s). An Administrator can assign roles, modify the site’s appearance, activate plugins, update WordPress, and do anything else that others can do.
The Editor’s Role
Editors can create, edit, delete, and publish their own (and others’) blog posts and pages; manage categories; moderate blog comments; and manage their user profile (nickname, email address, bio, password, etc.).
The Author’s Role
Authors can create, edit, delete, and publish their own blog posts and pages; and manage their user profile. They cannot manage categories or moderate blog comments.
The Contributor’s Role
Contributors can only create, edit, and delete their own blog posts and pages; and manage their user profile. They cannot publish anything.
The Subscriber’s Role
Subscribers can only manage their user profile.
* When using WordPress’ “multisite” feature to manage a network of WordPress websites, the Super Administrator has a higher level of responsibility.
