Snowflake Connection without DSN

You can use the Data Connection Manager (DCM) interface to capture all needed information and the driver to provide authentication. The data connection is shareable via Server, the connection string is saved in DCM instead of a workflow, and the workflow is shareable without being dependent on DSN.
