touchcueShows who is waiting for your security key touch

Early development. Works on Linux for FIDO2/U2F keys and OpenPGP cards through gpg-agent; not released yet.

Names the requester

The prompt shows the requesting application's name and icon and the device that is waiting.

A popup on Wayland (layer-shell) or X11 that takes no input focus, with desktop notifications as the fallback.

FIDO requests are tracked per CTAPHID channel ID, so a prompt stays until its own request ends.

A JSON event socket, a D-Bus service, and the socket protocol of yubikey-touch-detector.
