I think they mean that they want to be able to "recycle" the container, hence needing it to be abvle to have password changes.

Actually, I'm not wrong; ProGet is simply not designed for your use case. It is infinitely more stable in the use cases it was designed for. ProGet also can't bake you muffins; an "oven" is much more suited for this purpose. There are lots of tools that solve different problems, and ProGet is not designed as a desktop-based, single-user "server" for personal use. We have no intention of building such a tool; our tools are designed for teams to work together, not power tools for single users. Anyways, it looks like found the tool that you're looking for. Best of luck.
