I can create BlobServiceClient with the python SDK below. The "connection_string" is the connection_string I got from web console of Storage Account which including Access Key
blob_service_client = BlobServiceClient.from_connection_string(connection_string)

But now I don't have the access key of that Storage Account. What I have is a linked service to this Storage Account. And probably have SAS token or Service principle. But anybody could help how could I use linked service, SAS token or Service Principle to create BlobServiceClient with python?

    @Shao Peng Sun Thanks for reaching out to Microsoft Q&A. I understand that you are looking for creating Blob Service Client with either Linked service, SAS token or service principle. Please correct me otherwise.

    Please refer to the below code snippets-

    Create blob service client using a shared access key- https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/storage/azure-storage-blob/samples/blob_samples_authentication.py#L66

    Create blob service client using ClientSecretCredential- https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/storage/azure-storage-blob/samples/blob_samples_authentication.py#L88

    Create blob service client using Azure Identity- https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/storage/azure-storage-blob/samples/blob_samples_authentication.py#L125

    This doc shows how to construct the BlobServiceClient Class using SAS - https://learn.microsoft.com/en-us/python/api/azure-storage-blob/azure.storage.blob.blobserviceclient?view=azure-python
