Use best practices for managing users and groups to increase the security and manageability of your vSphere environment.

VMware recommends several best practices for creating users and groups in your vSphere environment:

Use vCenter Server to centralize access control, rather than defining users and groups on individual hosts.

Choose a local Windows user or group to have the Administrator role in vCenter Server.

Create new groups for vCenter Server users. Avoid using Windows built-in groups or other existing groups.
