Supported FIDO Devices
Overview
FIDO2 Web Authentication (WebAuthn) is a standard web API incorporated into web browsers and related web platform infrastructures used to securely authenticate users on the web across various sites and devices.
WebAuthn supports two different authentication mechanisms: platform authenticators and roaming authenticators (security keys).
Supported FIDO Devices
BlockID supports platform authenticators and security keys (also known as roaming authenticators).
Platform authenticators are built into your hardware and can often be unlocked using biometrics. Examples of platform authenticators include Touch ID and Face ID.
Security keys are separate pieces of hardware that connect to your device, such as a YubiKey.
Supported Browsers
FIDO2 and WebAuthn are currently supported in Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari web browsers.

WebAuthn is not supported on incognito browsers.
