Thank you for correcting the link you provided. It was unfortunately only partly helpful because the Application instruction given on the NitroKey site refer to Pam_p11 but the link suggested gives instructions for pam_pkcs11 which concentrate on CS Certificates.
Your installation instructions also suggest that the NitroKey App is at version 1.4 but when I go to the openSUSE link on your site it advises I uses the opensuse repo site. Unfortunately this only offers nitrokey-app version 1.3.2-1.61.
I mention this because I have had problems when logging into my computer when, even when no key is in the machine I get two NitroKey App windows opening and a log warning from a watchinf application.
I am willing to try and build the up to date version of NitroKey App if you could give me the link although I may have some problems. It would be better if you arranged for OBS to update their module. Would this be possible please?
