Contributors can author content in a site if they have been given permission to do so. In order to give a contributor authoring access to a site you have two options:

1. Add a group the contributor is a part of to the site's Site Users & Groups > Assigned Groups section.
2. Add the contributor to the site's Site Users & Groups > Assigned Users section.

This article will show you how to give a specific user permission to edit content in a site.

Note: We recommend using groups to manage site access permissions whenever possible.
