Roadmap
Authentication Strategy
Overview
This document outlines a comprehensive cross-platform authentication strategy for Zudoku, encompassing the documentation site, MCP Server, Mobile App, and CLI Tool. The strategy unifies authentication across platforms while allowing platform-specific adaptations for optimal user experience and security.
Core Protocols
Our authentication foundation uses OAuth 2.0 and OpenID Connect (OIDC) protocols:
- OAuth 2.0 for authorization flows and token exchange
- OIDC for identity information and JWT claims
- PKCE for public client protection
- Token rotation with refresh token flows
Identity Provider Architecture
We adopt a centralized identity provider approach with:
- Auth0 as primary IdP for enterprise-grade features
- Fallback providers (Azure AD, Firebase, Supabase) for specific use cases
- Self-hosted option using OpenID Connect compatible servers
- Tenant isolation for multi-tenant deployments
Platform-Specific Flows
Documentation Site
- Web-based OIDC flows with interactive login
- Session cookies for state management
- SPA routing with protected route guards
- Real-time token refresh via background calls
MCP Server
- API-key based authentication for programmatic access
- JWT bearer tokens for service-to-service calls
- Certificate pinning for secure transport
- Rate limiting with authenticated contexts
Mobile App
- System native authentication (biometrics, device unlock)
- App-specific OAuth flows with custom URL schemes
- Secure token storage in keychain/keystore
- Background refresh for continuous sessions
CLI Tool
- Device authorization flow (OAuth 2.0)
- Code grant flows for interactive sessions
- Token caching in secure OS key stores
- Automatic renewal without user intervention
Enterprise Security Requirements
Enterprise deployments must meet:
- SOC2/Type2 compliance for data handling
- GDPR compliance for data portability and erasure
- Encryption at rest and in transit using TLS 1.3+
- Audit logging of all authentication events
- Multi-factor authentication enforcement
Interoperability Mandates
Cross-platform compatibility ensures:
- JWT claims mapping across platforms
- Session synchronization for seamless user experience
- Federated logout terminating all platform sessions
- Token introspection for validation across services
- Role and permission propagation from IdP to downstream systems
Implementation Phases
Phase 1: Foundation
- Core IdP integration for web platform
- Basic CLI authentication setup
- MCP Server token validation
Phase 2: Enhancement
- Mobile app authentication
- Enterprise features (SSO, MFA)
- Advanced cross-platform tokens
Phase 3: Optimization
- Platform-specific UX improvements
- Performance optimizations
- Advanced security features
