Could you build this?
No Developing an open hardware security key involves embedded firmware development, cryptographic hardware acceleration, NFC antenna tuning, and compliance with FIDO2/WebAuthn standards.
What it would actually take: This project requires custom PCB design around Nordic's nRF52840 SoC, NFC antenna matching and RF validation, and embedded C/Rust firmware implementing CTAP2 and WebAuthn protocols. The hard parts include side-channel attack mitigation, secure key storage (using internal CC310 cryptographic coprocessors), and rigorous adherence to FIDO Alliance security certifications. It demands experienced embedded systems, RF, and hardware security engineers.
