A D-Bus proxy service lets sandboxed apps use CTAP2 authenticators without raw USB access by routing requests through a host agent that enforces per-device permissions and activates on demand via systemd. Implementation uses D-Bus proxy, libfido2 and TPM2 with xdg-dbus-proxy, an unnamed pipe forwards PINs from the app to the host, and demos show GitHub login from a Flatpak and an emulated passwordless flow; Firefox integration is implemented and awaiting review.
