I am pleased to report that upgrading the firmware on my second Nitrokey Storage device went well so both devices are now up to date so many thanks, got there in the end!
If I may impose on your time a little longer, I had hoped to be able to use one of my NitroKey devices for logging in, similar to what can be done with YubiKey. I am just beginning to use KeePassXC and thought I would ask the keepassxc authors if the NitroKey workd in a similar manner to YubiKey, which is supported on keepassxc.
I was surprised and disappointed to learn from the reply from keepassxc that the respondent apparently thought NitroKey was a simple USB memory stick and did not appear to be aware of the in-built capabilities of the NitroKey.
Can I use Nitrokey Storage in this way or should I use a different NitroKey model?
