OpenSK Dongle V2 | Open-Source FIDO U2F USB Security Key
To help and accelerate FIDO security key adoption, FEITIAN has designed a new PCB by removing unnecessary components and improved the OpenSK dongle casing, allowing users to build firmware from the Google OpenSK source code and using our open-source OpenSK hardware dongle to test and experience FIDO authentication.
What is OpenSK?
OpenSK is an open-source implementation developed by Google for security keys, written in Rust that supports both FIDO U2F and FIDO2 standards. Google's OpenSK open-source firmware, combined with an open-source USB hardware dongle, allows end-users to make their own security key to use for authentication and security.
