I gave a talk at the Infracoders Melbourne meetup about Consul. We ran short on time, so in the end I had to cull some stuff.
I gave a talk at linux.conf.au 2017 about Universal 2nd Factor (U2F), a method for two-factor authentication. This talk gives a brief history of two-factor authentication, some of the problems existing methods have, and then introduces U2F and how it solves some of these problems.
I gave a keynote at CompCon Australia 2016 about the history of and problems with passwords, and some of the things we can do to make the best of a bad situation.
I gave a lightning talk at YAPC:NA 2016 about Universal Two-Factor (U2F), a fairly new set of standards for building two-factor hardware devices, and Authen::U2F, a library you can use to add U2F support to your Perl application or web service.
