- in case of using S3 and Google Storage, we don't pass credentials and access keys we're using IAM roles and policies on Amazon and Service Account based access on Google Cloud
- in case of Azure the storage account name would be the dns prefix it's created (e.g. mystorage.blob.core.windows.net - the name would be mystorage), and you can you either the
