In WordPress, a Subscriber is a user role that has the lowest level of access and privileges. Subscribers can only view and read content on a WordPress site, and cannot make any changes or perform any actions on the site.
A subscriber can’t write, edit, publish content or upload files on your website.
When a user registers on a WordPress site, they are automatically assigned the Subscriber role by default. Subscribers can access their own profiles and make changes to their personal information, such as their name and email address.
Subscribers can also comment on posts and participate in discussions, but their comments must be approved by a higher-level user before they can be published on the site.
Overall, the Subscriber role is useful for site owners who want to allow users to view content and participate in discussions without having the ability to modify or publish content on the site.
