💡 This Skill requires execa, ora, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Auth0.swift is the official Auth0 SDK for Apple platforms. This skill adds complete native authentication to Swift apps using Web Auth (system browser redirect), secure Keychain credential storage via CredentialsManager, and biometric protection.

Core Features & Use Cases

  • Web Auth login using the system browser and Universal Links
  • Secure storage of credentials in Keychain via CredentialsManager
  • Biometric protection for credential retrieval
  • Integrated setup guidance for Auth0.plist and Associated Domains entitlements
  • End-to-end SwiftUI and UIKit integration patterns with real-world examples

Quick Start

Install the Auth0.swift SDK in your Swift project and configure a basic login flow with Auth0.plist.

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

FAQPage Schema
How do I add native Auth0 authentication to my iOS app?

To add native Auth0 authentication to an iOS app, you use the Auth0.swift SDK to implement Web Auth login via the system browser, storing credentials securely in Keychain with CredentialsManager and enforcing PKCE-based security.

How does Web Auth login work with Universal Links in macOS and iOS apps?

Web Auth login redirects users to the system browser for authentication, then uses Universal Links and associated domain setup to securely return them to your Apple platform app with PKCE-based security enforced.

Does Auth0.swift support biometric protection for Keychain credentials?

Yes, Auth0.swift supports biometric protection for Keychain credentials. The CredentialsManager retrieves stored credentials and requires biometric authentication before granting access to the secure credential payload.

What is the best way to configure Auth0.plist and callback URLs for Swift apps?

The best way to configure Auth0.plist and callback URLs is by defining your Auth0 domain and client ID in the Auth0.plist file, then matching those callback URLs with your Associated Domains entitlements for Universal Links.

Can I use Auth0.swift for authentication across tvOS, watchOS, and visionOS platforms?

Yes, you can use Auth0.swift for authentication across tvOS, watchOS, and visionOS platforms. The SDK applies universally across Apple platforms with identical Web Auth login and Keychain storage mechanisms.
