PERSONA: Justin Osborne - System_Architect
API Architecture Design for User Authentication
1. Presentation Layer
Structure: RESTful API
- Endpoints:
/auth/login/auth/register/auth/refresh/auth/revoke
Inputs & Outputs
/auth/login:- Input:
email@domain, password - Output:
JSON token (token), refresh token, user metadata
- Input:
/auth/register:- Input:
email@domain, password, additional_data - Output:
JSON token, user ID
- Input:
/auth/refresh:- Input:
refresh_token - Output:
New JWT token
- Input:
/auth/revoke:- Input:
token_id - Output:
User removed from system
- Input:
2. Business Logic Layer
Token Management
- Refresh Token: Valid for a short duration (e.g., 15 minutes).
- Renewal Flow:
- Input:
refresh_token, expiry - Output:
New token with updated expiry time.
- Input:
- User Revocation:
- Process based on user role and status.
Authentication Flows
- Login Flow: Auth2.0 (OAuth2.0) for stateless authentication.
- Register Flow: Client-Side Application (CSA) or server-side registration with hashed passwords.
- Refresh Token: Generated using a token manager, e.g.,
tokenmanager.js.
Rate Limiting
- Tools: Nginx, CloudFront for rate limiting and caching.
3. Data Access Layer
Database Store
- Use PostgreSQL or MongoDB encrypted with AES-256.
- RBAC (Role-Based Access Control) ensures sensitive data is only accessible by authorized roles.
Data Storage Strategy
- Database: Encrypt user credentials and store sensitive data in secure databases.
- Role-based Access: Define roles for user permissions.
