No Display? No Problem: Cross-Device Passkey Authentication for XR Devices

What this post added

Introduced a novel approach to cross-device passkey authentication for XR devices with inaccessible displays, bypassing QR codes. This solution leverages a companion app (Meta Horizon app) and push notifications to securely transport FIDO URLs, enabling passkey registration and authentication without an on-device display, while adhering to trust and proximity requirements.
