Why is the pin not entered on the device itself?

Hi there!

I am looking into devices and I was wondering as to why the nitro does not have 2 hardware buttons and a little screen where you can enter the pin? As I would assume entering the pin on any machine is a pretty big risk right?

Also for the U2F etc you could then confirm or deny the request to permit the action.

Thanks for any insights


at first the Nitrokey FIDO U2F does have a Button. Afaik it needs to be this way anyway regarding the standard.

Adding a numpad/display or similar to the other models would add a lot more complexity and most probably change the form factor among other problems. We therefore decided against such solution. Future Nitrokeys may have a single button, but it is unlikely that they will get a numpad/display.

Kind regards
