I wrote something on the new Nitrokey models, summarizing the last few newsletters: https://raymii.org/s/tutorials/Three_New_Nitrokeys_Pro_2_Storage_2_and_Fido_u2f.html.
Related to that, I have two questions.
I had to look into Fido and the different U2F options, which is quite confusing when you’re not into it (terminology wise).
Is it possible to add FIDO2 support to the Nitrokey FIDO U2F with a firmware update?
Will there be other Nitrokey models with a button forcing user interaction? (Press to confirm a PGP sign/action)?
