Hello, I'm following this tutorial: https://developer.android.com/training/sign-in/passkeys
It mentions the following required step: // Get passkeys from the user's public key credential provider. GetPublicKeyCredentialOption getPublicKeyCredentialOption = new GetPublicKeyCredentialOption(requestJson, preferImmediatelyAvailableCredentials); And then it gives an example of JSON request: { "challenge": "T1xCsnxM2DNL2KdK5CLa6fMhD7OBqho6syzInk_n-Uo", "allowCredentials": [], "timeout": 1800000, "userVerification": "required", "rpId": "credential-manager-app-test.glitch.me" } But it's not clear how to generate the "challenge" and what to put in "rpId". Any help would be greatly appreciated! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
