Last week we discussed the basics of two-factor authentication (2FA) and we wanted to delve deeper into one of its methods that go beyond SMS and app-based authentication. The FIDO U2F keys act like secure pen drives you can use for two-factor authentication and the best part of all, they are less than $20.
When I mentioned to a few friends that I was writing a feature about two-step authentication, the typical response was an eye-roll and "Oh, that annoying thing?..." We've all had that thought when we needed to get a code before we could verify our identity online. However, after much research about two-factor authentication (often referred to as 2FA), I don't think I'll roll my eyes at it anymore.
