OpenSK FIDO2 Authenticator¶
OpenSK is based on the FIDO2 specifications, which combine the World Wide Web Consortium’s (W3C) Web Authentication (WebAuthn) specification and FIDO Alliance’s corresponding Client-to-Authenticator Protocol (CTAP).
The nRF52840 MDK USB Dongle is supported by OpenSK. Taking advantage of the UF2 Bootloader, you can easily program the OpenSK firmware by just copying the
.uf2-format image to the flash drive.
We think the best way to learn is by doing. The following sections take you through the basics of OpenSK and show you how to build your own OpenSK firmware.
