Frequently Asked Questions about authentication

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement Sign in with Apple using AuthenticationServices?▼

Implement Sign in with Apple by configuring AuthenticationServices to handle Apple ID credential requests. This provides privacy-protected authentication and requires iOS development experience to integrate the framework correctly.

What's the best way to support passkeys for passwordless iOS authentication?▼

Support passkeys by implementing WebAuthn flows within AuthenticationServices. This enables secure passwordless sign-in, leveraging device biometrics to authenticate users without traditional password inputs.

How does biometric authentication work with LAContext for local re-authentication?▼

Biometric authentication works with LAContext by evaluating local device security policies. It enables Face ID or Touch ID checks to securely re-authenticate users for sensitive operations.

Do I need iOS development experience to use ASWebAuthenticationSession for OAuth?▼

Yes, iOS development experience is required. ASWebAuthenticationSession handles OAuth flows by launching a secure browser context, demanding familiarity with Apple's authentication frameworks to manage token validation.

How do I validate identity tokens for server-side authentication?▼

Validate identity tokens by verifying the cryptographic signature and claims on your backend. This ensures the token received from AuthenticationServices is authentic and securely maps to the user's Apple ID.

What are the security boundaries when handling iOS authentication tokens?▼

Security boundaries dictate that sensitive tokens must not be exposed to untrusted contexts. Best practices involve securely storing credentials and validating tokens server-side to prevent unauthorized access.
