Is the blue Security Key C NFC by Yubico supported as one of the Security Keys for iCloud login ?
I tried activating the security keys I have in Apple's newly released Security Key features in Ventura 13.2 and iOS 16.3, but on both platforms the wizard for adding the keys fails in the second step where I need to confirm my password once more.
