It was only a matter of time before we had Wendy Nather from Cisco Secure Duo on the show. We finally met Beers with Talos’ level of stardom, as Wendy joins the show to discuss SMS messages as a form of multi-factor authentication. We break down why SMS authentication is still around and used by some of our most important services like banks, and what alternatives are out there. We also discuss the dangers of SIM-jacking attacks and the benefits of using Duo’s app-based authentication.
