Today I am very excited to announce that Azure service principal has been added as an authentication type for a set of data sources that can be used in Dataset, Dataflow, Dataflow Gen2 and Datamart. 

Azure service principal is a security identity that is application based and can be assigned permissions to access your data sources. Service principals are used to safely connect to data, without a user identity. Learn more about service principals.
