A PoC for a WebAuthn-based flow to join anonymous Semaphore groups. Essentially using WebAuthn as a cross-device wallet for your Semaphore identities in a way that is more convenient and secure than a password manager. Integrated with IYK's NFC devices to make creating in-person groups smoother than the individual QR codes used at Devcon's TAZ.
The end goal is to clean up this repo and set up a well-documented and well-organized starter repo for future message-board style apps. WebAuthn's biometric based authentication is smoother and more secure than localStorage, chrome extensions, or password manager based solutions.
This has now been merged into the core Semaphore repository: https://github.com/semaphore-protocol/semaphore/tree/main/packages/heyauthn !
