Could you build this?
No A DIY FIDO2 hardware security key requires embedded hardware design, USB and security firmware, and secure key storage, which are beyond vibe coding alone.
What it would actually take: Start from an existing open-source FIDO2 firmware such as pico-fido on an ESP32-S3 board, then add an ST7735 display driver and wiring. Making it a trustworthy security device needs embedded firmware expertise, knowledge of secure-element and key-protection practices, and hardware testing for USB enumeration, FIDO certification conformance, and side-channel resistance.
