The CARTO Enterprise account service provides multiuser(MU) environments, where users can upload datasets securely, share them with specific team members, or publish them directly on the web. With Enterprise accounts, no custom software installation is required. Your group can continue to access the web-based CARTO Builder and work alongside colleagues. Optionally, authenticated organization administrators can use the Enterprise User Management API to manage users programmatically.
