This is a proof of concept for what I'm calling Dynamic Preauthentication. Essentially, a precompiled executable keeps a constant time string that has a known (or easily extracted) pattern.
When a download is requested, the server can generate and embed a token that allows the application to authenticate the user immediately.
This would allow users to skip the initial login process and immediately start using the application. It could also be used to track downloads, hint at user behaviors, or create unique user experiences.
