Each NSX-T appliance has three local accounts, admin, audit, and root. To administer NSX-T, you must log in as admin.
The root user has special privileges. You must not log in as root and make changes that are not documented in this guide, except when under the guidance of VMware. Changes made by the root user can cause catastrophic failures. In a production environment, the root password should be secured and made available for privileged access only.
