Select this check box to use a shared access signature (SAS) to access the storage resources without need for the account key. For more information, see Using Shared Access Signatures (SAS).

In the Azure Shared Access Signature field displayed, enter your account SAS URL between double quotation marks.

For more information, see Constructing the Account SAS URI.

Note that the SAS has valid period, you can set the start time at which the SAS becomes valid and the expiry time after which the SAS is no longer valid when generating it, and you need to make sure your SAS is still valid when running your Job.
