This library implements a simple, basic WebAuthn client and server based on duo's WebAuthn implementation. The code pulls inspiration from duo's WebAuthn example implementation. This example is NOT meant to be used in production, but rather as an introduction to WebAuthn as well as a more quick-and-dirty, stripped down version of webauthn.io.

Download the project (i.e. via git clone or go get) and navigate to the project's root directory.
Start the server by compiling and running the code. It should look something like this:
$ go run .

Upon successful registration, you'll see an alert saying you successfully registered, similar to this:
Press the login button and follow the instructions. The login process is identical (user side) to the registration process.
In your Chrome broswer go to chrome://flags/ and search for 'web auth', then set 'Web Authentication API BLE support' and 'Web Authentication caBLE support' to enabled
