An outside collaborator is a person who isn't explicitly a member of your organization, but who has Read, Write, or Admin permissions to one or more repositories in your organization.

Only members with owner privileges for an organization or admin privileges for a repository can add outside collaborators to a repository.

If your organization requires members and outside collaborators to use two-factor authentication, they must enable two-factor authentication before they can accept your invitation to collaborate on an organization repository.

When you add an outside collaborator to a repository, you'll also need to add them to any forks of the repository you'd like them to access.
