I am having the same problem!
The windows start to ask me about this security key unexpectedly.... I tried to disabled it in the cofiguration of my windows account but it asked me to put the USB with this security key that I have never created in my life!
I lost access to a lot of we accounts that was connected with my windows PIN, because now its asking me this security key to entry in those websites as well.
I have tried to get help from the support team but anyone can help me because they say that it is a "hardware problem" and I need to call a hardware technical support to solve it, do you believe?!
