What I don't understand is how the feature set of this key can be still this underdeveloped. I'm desperately seeking an (open source) key which does FIDO2 passwordless auth, ed25519, PGP and can function with older SSH implementations (smartcard compatibility). All of the above are on the "may be implemented" list. None of the above except FIDO2 have happened in the additional year of development time. It's one thing to have a hardware shortage, but this should not stop software development. Even changing the microcontroller involved should not delay feature development this long - both are standard ARM cores, and emulators are a thing. Yet, there are half a dozen new products appearing - all of which obviously needed software development time. I always thought that hardware tokens are the most important product for nitroKEY, seems I was mistaken.
