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.

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.

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.

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.

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.

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.
