Difference between system admins and Quest device admins in Admin Center
All admins have to be 18 years of age or older (depending on the age of legal majority where they reside) and use a verified or trusted domain.
System admins
System admins have all permissions available in Admin Center. System admins can also create and assign custom admin roles.
Each organization using Admin Center must have at least 1 system admin.
If your organization is giving another organization access to your Admin Center, then you can choose to grant an External system admin role. External system admins have all available permissions in your Admin Center apart from being able to manage external relationships hosted by you and view security logs and alerts.
Quest device admins
Organizations that subscribe to Meta Quest for Business have access to the Quest device admin role. Quest device admins have all permissions relevant to managing Meta Quest for Business devices in Admin Center.
