If I’m Already an Approved Partner, How do I Add Additional Users to the Portal?Read article
As an approved partner, new users can register (self-serve) on this page. Select “sign up” and be sure to use your company email address. After entering your email address, you’ll be prompted to confirm the organization you belong to. Login instructions will be sent to the email address provided.
Alternatively, partner admins can manually add new users in the portal.
