# What access privilege is needed for the supporting VMware credential while discovering vCenter servers?

- All credential user types (Read only user, admin, etc.) are supported for VMware discovery in **OpManager**.
- Ensure that the credential being used **has access to all VMware hosts/VMs under the vCenter server.**
- Using a **Read only** type credential will enable the user to only monitor VMware resources; workflow-related functionalities cannot be performed on the VMware devices.
- **Admin** type credentials are required to perform all types of VMware tasks and workflow functions.
