And this is really off topic for this list.

General Tor energy bits moved here... https://lists.torproject.org/pipermail/tor-talk/2019-June/045256.html re 305 etc It wouldn't be unusual for an app to pop up some form of captcha, challenge, or data exchange where needed. Some of that model exists in form of onion service authentication config... some helper data that grants access, makes things happen, whether passive or active interrupt. The controller would be the interface. Yet tor currently has no mechanism on platforms to handle such protocols and popups... thus like onion auth, the user has know they need it for something and configure it in advance. Try investigating an ssh-agent like tor tool... preloaded with users Proof-of-*, 2FA, consumables, etc to dole out, even automatically, where needed and permitted.
