I regularly use 5 different data sources in Tableau Prep, and every time I want to start a new data flow I have to retrieve the connection information from a password manager and enter the information by hand for each connection.

I would love the ability to embed authentication and save connection settings so that I don't have to do all of that work by hand. One workaround I've tried using is a "Template Workflow" that includes all of those connections, but it still doesn't have the ability to embed credentials so I'm stuck doing the back-and-forth again each time.

At the end of the day I can get where I need to go the long way, but considering the ease with which you can save data sources in Tableau Desktop I would love a similar experience in Tableau Prep.
