Webauthn is the latest standard for secure, scalable, passwordless authentication on the web. This talk will describe the protocol from the point of view of the Browser and Authenticator, not the Relying Party (so we won't cover how to build a webauthn enabled website, we will cover how to get a Linux laptop with a TPM to be able to take advantage securely of webauthn enabled websites). In the next part of this talk we'll give an overview of Linux USB gadgets and how they work (from the point of view of people wanting to use them, so no kernel internals experience necessary) and Finally we'll describe how to build a webauthn authenticator "token" using the Linux HID Gadget and TPM version 2. The source code for this project is available at https://git.kernel.org/pub/scm/linux/kernel/git/jejb/fido2-ctap-gadget.git/.
