Facebook is using the YubiKey 4 Nano for securing its own staff. In January 2017, Facebook made support for FIDO U2F for its entire user base (1.8 billion users).
“Facebook is a very fast paced environment and we needed technologies that would allow us to maintain that pace. Because of the ease of use of Duo Security and Yubico authentication technologies, we have seen minimal support and overhead costs. Other technologies, such as traditional OTP-based hardware tokens, smart cards, and biometrics didn’t fully support our need to allow multiple and rapid logins to SSH sessions.”
John “Four” Flynn, Information Security Manager, Facebook Inc., USA
“We’re excited to offer security keys as an additional option to make login to Facebook even more secure. We’re grateful to Yubico for the support and feedback they’ve provided.”
Brad Hill, Facebook Security Engineer.
