We are trying to add full support for iOS password autofill (with suggested credentials) with Auth0 for traditional UN/PW login, and share stored credentials between our mobile app and web login. According to the documentation, we are required to support webcredentials in a apple-app-site-association via the associated domain. For reference, see: https://developer.apple.com/documentation/security/password_autofill/setting_up_an_app_s_associated_domains
From what I see, it is possible to configure this file for the auth domain (myapp.auth0.com, or, custom domain) in the auth0 app advanced settings, but only for applinks. But I can see no way to specify webcredentials.
Am I on the right track? Is there any documentation on how to set this up or is this even possible? iOS password autofill has been a standard feature for some time, I would hope that I am able to take advantage of this functionality.
