Hi @antonionardella,
did you try / manage to use your FIDO2 device with the librem5?
I would be very interested of your results. I am also owning a FIDO2 device using it to decrypt my desktop devices. As I created a rather long encryption password this would be a convenient way to startup my phone. However I don’t want to brick my phone - so if you already made your experience - sharing would be appreciated.
As the question arose during the thread - my librem 5 has systemd version 247.
Kind regards
