authentication

Implement Sign in with Apple on iOS using the AuthenticationServices framework to initiate the native flow, process user authorization, and securely manage credentials for your app's login system.

ASWebAuthenticationSession manages OAuth login flows by opening a secure web view for third-party authentication, capturing the redirect response, and securely passing the authorization code back to your iOS app.

Yes, you can use iOS Keychain for Password AutoFill by securely storing user credentials and associating them with your app's associated domains, allowing iOS to suggest saved passwords during sign-in.

The best way to add Face ID and Touch ID biometric authentication on iOS is using LAContext to evaluate device security policies, prompt the user, and securely gate access to sensitive app features.

Yes, iOS authentication requires state checking to ensure secure credential handling. You must validate the user's current authorization state with AuthenticationServices to maintain secure access to user accounts.

You should use ASWebAuthenticationSession instead of native Sign in with Apple when your iOS app requires third-party OAuth integration for services like Google or GitHub that need standard web-based authentication flows.
