Bringing U2F to the Masses


#1

Universal 2nd Factor (U2F) is a second factor for authentication that uses public key cryptography to authenticate users. Duo has supported U2F since 2014, which (until now) has always been in the form of external keys, which causes some barriers in adoption for many businesses.

Duo Labs has partnered with Intel to bring native U2F support to Windows computers without the need for additional hardware. Intel implemented their U2F client in software by randomly generating a square on a screen that the user must click on to fulfill the user presence test
