I have no problem accessing 2FA enabled web sites from my "production" PC but I just tried it from a laptop and got a very intrusive popup.

I know without Windows telling me; the web site - PayPal, in this case - tells me, and tells me what method it expects me to use. Picking "Security key" and clicking "Next" just adds unneeded steps. Picking the wrong option or clicking "Cancel" prevents the security key from being detected. The popup identifies itself as "Windows Security" but there's nothing in the Windows Security settings that seem related to this. I use BitDefender as my security package, but I see nothing it it related to this. (Anyway, BitDefender loves to brag about all the good work it does. It would certainly put its name all over the popup if it were involved.)
I haven't tried this on all the computers in the household, but it's not a problem on 2 of them. They happen to be Ethernet-attached to the LAN rather than wireless. I just tried Ethernet-ataching the laptop but the popup still appears.
What can I do to get rid of this popup?
