@Andy R Welcome to Microsoft Q&A, Thank you for posting your query!
- You can use Azure File service in your scenario. Azure Files offers fully managed file shares in the cloud that are accessible via the industry-standard Server Message Block (SMB) protocol and the Network File System (NFS) protocol (preview). You can mount Azure file shares concurrently on cloud or on-premises deployments of Windows, Linux, and macOS. You also can cache Azure file shares on Windows Server machines by using Azure File Sync for fast access close to where the data is used.
To learn more about the scenarios that Azure Files can help you with, see Why Azure Files is useful.
Azure files uses different types of authentication (AAD, Shared Key, RBAC) , see here for detailed information on authorizing access to data in Azure Storage
