Definitely intrigued by McAfee beyond the stories of suspicious activity

However, what's a little troublesome about the website is the lack of deeper technical specs on this "key". I couldn't find any FIDO ( https://en.wikipedia.org/wiki/FIDO_Alliance) references which is important and none of the password managers seem to be supporting.
Granted I like the Bluetooth-AUTH innovation vs. NFC (YubiKey), I haven't seen this tested in a lab yet.
Anyone going to BlackHat this Month?
