The owner role must be assigned to an administrator before it may be added to the Azure portal. It will only be able to control the subscription's resources that have been assigned to it. These are the steps to add an administrator:
i. Firstly, to use the Azure portal, go to https://azure.microsoft.com/en-in/features/azure-portal/ and sign in.
ii. Then, select the Hub menu followed by Subscription, and select the subscription that the administrator will need access to.
iii. In the subscription blade, select Access control (IAM) and then click Add.
iv. Select Owner from the drop-down menu under Select a role.
v. In this field, enter the email address of the user who will be designated as the owner.
vi. Select the user by clicking on his or her name.
