SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mobile apps face complex authentication requirements that protect user identities and keep sessions secure across devices.

Core Features & Use Cases

OAuth2 PKCE flows: Implement secure authorization without client secrets on mobile.
Biometric unlock and secure storage: Local biometrics-backed access to tokens with strong storage guarantees.
Social login integration: Support Google/Apple/Facebook sign-in to streamline onboarding.
Token management & session security: Rotate tokens, manage sessions, and guard against token leakage.
MFA and security auditing: Add MFA options and provide a checklist for security audits.

Quick Start

Provide a complete, secure login flow for a mobile app using OAuth2 PKCE, biometrics, and social sign-in.

Frequently Asked Questions about mobile-auth

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

FAQPage Schema

How do I implement OAuth2 PKCE for secure mobile authentication?▼

OAuth2 PKCE secures mobile authentication by using a dynamic code verifier and challenge instead of a static client secret. This Skill designs the complete PKCE flow, ensuring secure authorization without exposing secrets in your React Native, Flutter, or native iOS/Android app.

What is the best way to integrate biometric unlock with token storage in a mobile app?▼

Biometric unlock gates access to securely stored tokens using device hardware. This Skill designs an architecture that binds local biometrics to strong storage guarantees, ensuring tokens remain protected even if the device is compromised.

Does this approach support social login integration with Apple Sign-In for iOS?▼

Yes, social login integration explicitly includes Apple Sign-In alongside Google and Facebook providers. This Skill streamlines onboarding by mapping social provider tokens into your centralized session management and security guardrails.

How do you handle refresh token rotation and session security for mobile apps?▼

Refresh token rotation prevents token leakage by issuing a new refresh token on every use. This Skill designs token management workflows that actively rotate tokens, manage active sessions, and enforce guardrails against unauthorized access.

Can I use this architecture to perform a mobile app security audit?▼

Yes, this Skill provides a comprehensive checklist for security audits alongside the authentication design. It evaluates your mobile login flows, PKCE implementation, token storage, and biometric gating against strict security guardrails.

Do I need a client secret for OAuth2 social login on React Native and Flutter?▼

No, mobile apps should not store static client secrets. This Skill enforces PKCE to secure OAuth2 social login flows across React Native, Flutter, and native platforms, eliminating the need for client secrets while maintaining authorization integrity.
