You must set up a root account for vSphere Replication. The root account is used to access both the virtual appliance console and the Virtual Appliance Management Interface (VAMI).
vSphere Replication currently uses the root account as the administrator of the VAMI. No other user is created.
When you deploy the vSphere Replication virtual appliance, you set the password for the root account in the OVF Deployment wizard.
The root password must be at least 8 characters long.
Privileges Assigned to Default User Roles
vSphere Replication includes a set of roles. Each role includes a set of privileges, which allow users with those roles to complete different actions.
See the topic vSphere Replication Roles and Permissions in the VMware vSphere Replication Installation and Configuration Guide.
