Hi,
I recently got myself a Yubikey (well, two) and I only intend to use it with KeePassXC, I’m not intending to log into any online services with it.
I looked through the U2F proxy documentation here: U2F proxy | Qubes OS and got the impression that U2F proxy is intended for browser interaction and not yet appropriate for using with KeePassXC or other offline apps inside a vault qube. Did I interpret that right?
