"via an adapter" what do you mean by that? It could be that the Yubikey is being locked by another application as well.

[greaka]

I tried "everything". Closing every Program that is able to use this key (Except Windows itself for example).
I can hit reload and the loading indicator goes off for a couple of seconds but thats it. When i remove the key, the loading indicator doesnt even appear.
As I said, other Programs can use it, even almost simultaniously

The "via an adapter": usb A 2.0 port in notebook -> male 3.0 A to female 3.0 C adapter -> yubikey 4c

the adapter is a 1 to 1 bridge. no multiple inputs etc. It is almost as small as the key itself

You could try testing if the key itself works with their own software first:

If you wish, I can create you a video how I log in to github, google, windows, how I sign git commits with it. It is working. I have the yubico tools installed and also successfully configured my key with them

My bad, I didn't notice you already said it twice it works fine with everything else.

I guess my next question is have you configured one of the slots in the Yubikey for HMAC-SHA1 Challenge-Response?

Thank you for this link, i didn't find any tutorial before and thought I don't need any further configuration!
Thank you all for your help :)

[droidmonkey]

I think we should display a notice saying to configure the yubikey, I'm going to leave this open cause there is a discoverability issue here.

The new database settings widget in my wizard PR already contains links to documentation about setting up your YubiKey properly
