It's a few months away, but we'll have usb-c + nfc in Solo (open source security key supporting FIDO2). We'll launch the Kickstarter next week: https://solokeys.com
We're starting FIDO2/U2F only, but we'll have the possibility to upgrade the firmware. PGP/SSH are the top feature requests, so we'll add them right after the Kickstarter -- unless the community builds them first.
Ciao Emanuele, just dropped a linkedin connection request. I am working on a product that would benefit from solo, would love to pick your mind sometime in near future.
