  🗒️ Ideas, thoughts, and general notes (by AnandChowdhary)

I love the idea, I had a similar one two years ago (https://github.com/AnandChowdhary/notes/blob/main/notes/2018...) to use “face unlock” but as an MFA method.

The one problem I had was that face detection using the webcam is not be accurate, e.g., it can be easily fooled using a printed photo of the person or changing the webcam input to use a static photo. With WebAuthn, however, this is not possible because it connects to the device’s native authentication. On macOS, for example, it’s much harder to spoof Touch ID.

How would you go about preventing such problems? Isn’t it better to provide an Auth0-style SDK to use WebAuthn with SSO, or do you think using this cloud based image recognition system is as foolproof as the native options?
