Assign a user as an administrator of an Azure subscription

To make a user an administrator of an Azure subscription, assign them the Owner role at the subscription scope. The Owner role gives the user full access to all resources in the subscription, including the permission to grant access to others. These steps are the same as any other role assignment.

Step 1: Open the subscription

  1. Sign in to the Azure portal.

  2. In the Search box at the top, search for subscriptions.

  3. Click the subscription you want to use.
