Recently there is the possibility to verify a login with FaceID or TouchID. This is explained here https://developer.apple.com/videos/play/wwdc2020/10670/.
Currently I can't find complete sample codes, but https://webkit.org/blog/11312/meet-face-id-and-touch-id-for-the-web/ is a good place to start.
Unfortunately, I don't quite understand yet from what the variable "challenge" results. Do I have to generate a new random 32 character long value for each challenge?
I also don't understand how the value of the variable credentialIdBuffer1 is calculated.
I think I am not the only one who has these questions and others might find their answers here.
I would be very grateful for your help. Best regards
