Before you assign it

  • It can give access to others. It allows Microsoft.Authorization/roleAssignments/write, so treat it as a privileged role and assign it through PIM where you can.

What it can do

PermissionWhat it allows
*/readEvery operation matching */read
Microsoft.Authorization/*Every operation under Microsoft.Authorization
Microsoft.Support/*Every operation under Microsoft.Support

Assign it

Scope it as tightly as you can: a resource or resource group rather than the whole subscription.

azure cli
az role assignment create \
  --assignee "jane.doe@contoso.com" \
  --role "User Access Administrator" \
  --scope "/subscriptions/<subscription id>/resourceGroups/<resource group>"
