## Security Features Implemented

1. **Token Security**
   - Access tokens expire in 15 minutes
   - Refresh tokens expire in 30 days
   - Token rotation prevents replay attacks
   - Logout immediately revokes tokens

2. **Password Security**
   - PBKDF2 algorithm (RFC 2898)
   - 100,000 iterations (OWASP compliant)
   - Random salt generation
   - Secure password comparison

3. **Access Control**
   - JWT middleware for protected routes
   - Bearer token authentication
   - Automatic token validation

---

## Testing Status

### Unit Tests
⏳ **Pending** - Implementation complete, ready for unit test creation

### Integration Tests
⏳ **Pending** - Test file created, requires MongoDB connection
``ash
# To run integration tests:
cargo test --test auth_tests
```

### Manual Testing
✅ **Script Created** - thoughts/test_auth.sh
``ash
# Start MongoDB
docker run -d -p 27017:27017 --name mongodb mongo:latest

# Set environment variables
export MONGODB_URI="mongodb://localhost:27017"
export DATABASE_NAME="normogen"
export JWT_SECRET="your-secret-key-min-32-chars"

# Start server
cd backend && cargo run

# In another terminal, run tests
./thoughts/test_auth.sh
```

## API Endpoints

### Public Endpoints (No Authentication)
- `POST /api/auth/register` - User registration
- `POST /api/auth/login` - User login
- `POST /api/auth/refresh` - Token refresh
- `POST /api/auth/logout` - Logout
- `GET /health` - Health check
- `GET /ready` - Readiness check

### Protected Endpoints (JWT Required)
- `GET /api/users/me` - Get user profile

## Deferred Features (Future Phases)

| Feature | Target Phase | Reason |
|---------|--------------|--------|
| Rate Limiting | Phase 2.6 | Governor integration complexity |
| Token Version Enforcement | Phase 2.5 | Not critical for MVP |
| Permission Middleware | Phase 2.5 | No multi-user support yet |
| Password Recovery | Phase 2.4 | Zero-knowledge phrases |
| Email Verification | Phase 2.4 | Email service integration |

---

## Next Steps

### Phase 2.4 - User Management Enhancement
- Password recovery with zero-knowledge phrases
- Email verification flow
- Enhanced profile management
- Account settings endpoints

### Immediate Actions
1. Run integration tests with MongoDB
2. Test all authentication flows manually
3. Implement Phase 2.4 features
4. Create comprehensive unit tests
