Final answer:
The ability to manage user access to resources across multiple subscriptions in Azure is facilitated by Azure Active Directory (AAD), which is a cloud-based identity and access management service.
Step-by-step explanation:
The ability to manage user access to resources across multiple subscriptions in Azure is provided by Azure Active Directory (AAD). AAD is a cloud-based identity and access management service that helps your employees sign in and access resources in:
- External resources, such as Microsoft Office 365, the Azure portal, and thousands of other SaaS applications.
- Internal resources, such as apps on your corporate network and intranet, along with any cloud apps developed by your own organization.
AAD allows for centralized management of users, providing secure access and enabling multi-factor authentication, among other security measures.
