Hi Juan and everyone.

Smart Card support which is already a hardware standard and it is well know
what language it speaks (ISO7816) should be considered as an alternative to
new and yet to be common U2F hardware standard.

As you all know smart cards are not only already a standard, it has sold in
the billions and costs as little as $0.60.

In addition,  Public key methods (without using PKI) is already well
supported with repurposed smart card security applets such as PKCS #15 that
can work with existing server infrastructure with very minimal change, to
enable for eg mutually authenticated TLS connection with no need for
3-party PKI. We already have this working in Firefox where the smart card
is connected to the device in one of many possible ways.

Not to mention smart card applets are extensible to any future standard
such as the yet to be released NIST standards on derived credentials for
government use.

In addition smart cards are the only security hardware that have well
defined and well followed security certification across multiple industry

It would be unproductive to consider hardware without smart cards as part
of it.

Dear Harry - What is the expected timing of considering hardware extension?
We will take ownership in writing an alternative to U2F that is smart card
