Auth.Jc

Full-stack auth demo with Apple Sign-In, Google Sign-In, GitHub Sign-In, and others. Face ID / Touch ID login and automatic JWT token refresh.

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.
