Quite neat. Though I'm still dissapointed in the U2F/Security Key market. The Yubico's cost 50€ the piece or 20€ for the U2F key only. And to get NFC usage you have to buy a worse variant of the other keys that doesn't support 4096bit RSA and some other features. There is not much competition either, Nitro is just as expensive and doesn't feature a good and cheap key either. Open Source variants are also fairly rare, I would love to DIY some Yubikey 4-like stick with the same or similar/comparable function set. Only thing so far I found is the U2F zero but that didn't offer RSA. Quite annoying, maybe some competitor other than Yubikey and Nitro can solve this. (It doesn't seem Google is selling the Titan, I see no pricetag)
