AZR - Shared Access Signature

A shared access signature (SAS) provides secure delegated access to resources in your storage account without compromising the security of your data. With a SAS, you have granular control over how a client can access your data. You can control what resources the client may access, what permissions they have on those resources, and how long the SAS is valid.

When a client proxy or user needs direct access, you can provide customized access.

Customize which specific access you want to give to any user or client


Generate SAS and share with client to access
