## What is Auth.Jc?

Auth.Jc is a full-featured authentication demo built with React Native. It showcases a production-ready auth stack with multiple sign-in methods, secure credential storage, and a polished iOS UI.

Sign-In Options
• Apple Sign-In (iOS only)
• Google Sign-In
• GitHub Sign-In
• Email and password
• Biometric login — Face ID and Touch ID

Security
• JWT access and refresh tokens with automatic refresh interceptor
• Credentials stored in the device Keychain — never in plain storage
• SSL certificate pinning
• Rate limiting on login and password reset attempts
• Input sanitization and XSS prevention

Features
• Push notifications via Firebase Cloud Messaging
• Deep linking for password reset flow
• Dark and light themes with multiple color palettes
• Profile editing with photo upload
• Localization — English and Spanish
• Portrait-optimized for iPhone

Auth.Jc is an open-source portfolio project demonstrating modern React Native architecture. It is not a production identity provider.
