I know that there are discussions in the SSL community about providing
two-factor authentication. Some DNS registrars (name.com for example)
offer two-factor authentication to customers (I am one of them who
uses two-factor authentication with them).

I am not sure the time is right for requiring POCs to use two-factor
to authentication to ARIN, but it is probably a good time for ARIN to
offer it as an option.

I am particularly in favor of Google's approach. They make use of an
open standard (OATH, RFC4226) and the customer gets to download their
token seed (yes, this is a risk) which you can load into a smart phone
based authenticator (or write your own code, as I have done). Google
also creates a set of "scratch" codes which you are told to print and
keep in a safe place. They can be used in lieu of an OATH code, in the
case where you lose your phone. Of course part of Google's model is to
avoid people having to contact Google's customer service to reset
their account if they lose their tokens.

It is also a low cost solution compared to other token vendors which
charge $$ for the tokens (even a "soft" token loaded into a smart
phone) or require you to validate customers via a web server they
operate and charge $$ for.
