Hi @alkhleif_2585 ,
There isn't much demand for this kind of feature (I think we've only seen one or two requests for this over very many years) so it's not on our roadmap.
And it's unlikely we will add it to the roadmap considering that it would be quite costly to build, support, and maintain. Especially considering that we'd need to support all of the major "vaults" out there as well.
It doesn't seem to add much value to ProGet as these types of read-only credentials can be very long living (several years) without any security risk, and take just a few minutes to rotate when needed.
That being said, you could probably write a "sync script" pretty easily that continuously updates the connector credentials by connecting to the vault and then updating it via the API.
Cheers,
Steve
