Passkey demo app

[taozuhong]

I tried to integrate with libfido2 on Windows, but I don't know how to use it. like:
1、Enum available devices (select.c)
2. Register credential with the device (Windows Hello)
3. Authenticate with this credential (launch Windows Hello UI)
4. Update and delete the credential

Could anybody share a minimal example app to do it?

Hi,

1. Enum available devices (select.c)

On Windows, unless you're running as a privileged user, you have to use the windows://hello pseudo-device. It will handle authenticator selection for you. As a privileged user, examples/select.c should mostly work (you'll probably have to add code to ignore the windows://hello pseudo-device).

2. Register credential with the device (Windows Hello)

Please see examples/cred.c.

3. Authenticate with this credential (launch Windows Hello UI)

Please see examples/assert.c.

4. Update and delete the credential

I'm not entirely sure what you mean by "update the credential" in this context. Note that the windows://hello pseudo-device does not implement credential management (AFAIK, such an API is not exposed by Microsoft) -- the only way around this is a privileged application with direct access to the device.

Got it, thanks.

I'll try it immediately.
