nRF52-U2F is an open-source FIDO U2F implementation on nRF52 SoC. Taking advantage of Nordic’s powerful SoC nRF52840 and nRF5 SDK, it's quite easy to make a FIDO U2F key with a number of distinguishing features, such as USB HID class modules, comprehensive cryptography library with ARM TrustZone Cryptocell-310, reliable Device Firmware Update (DFU), etc. The FIDO Universal 2nd Factor (U2F) is an open authentication standard that allows online services to augment the security of their existing password infrastructure by adding a strong second factor to user login. During registration and authentication, the user presents the second factor by simply pressing a button on a FIDO U2F key. The user can use their FIDO U2F key across all online services that support the protocol leveraging built-in support in web browsers. FIDO U2F has been successfully deployed by large scale online services, including Google, Facebook, Twitter, GitHub, GitLab, and many more. The FIDO U2F technical specifications are hosted by the open-authentication industry consortium known as the FIDO Alliance. Learn more about U2F on
