Dear all,
I am using a sys-usb. All are working well even the U2F with a yubikey.
I have installed the tar.gz authenticator on the template I am using for my work qube.
When running the authenticator, II have a “no yubikey present” message.
When connecting my yubikey to my Qubes pc, I have : “1050:xxx_yubikey_NEO_… NEW”
Thx
The Yubikey Authenticator access the Yubikey via PCSC, that is not U2F (different protocol and method).
You have to connect the yubikey directly to the app qube, where the authenticator is running.
Thx a lot, it is working 
I do have another question, is there any possibility to add the authenticator app to the available application list of my Qube ?
Thx
Yes, there is a script in the authenticator folder, desktop-integration.sh.
You have to call it on the app qube with --install as parameter.
But on my system, it was only working after i have created
“~/.local/share/applications” folder.
Then, the authenticator application can be added like any other application to the list.
Ok, Like you, I have hadd to create the folder, run the script, but I do not have autenticator in the list, have you install it in the appvm or in the template of the app vm ?
done, it is on the list. thx agazin.
