# Component: PasswordService
## Responsabilidad
Gestionar el cambio de contraseña de usuarios autenticados. Validar contraseña actual, verificar requisitos de seguridad de la nueva contraseña, y invalidar sesiones existentes.
## Tipo
- [x] Microservicio
- [ ] Library/Biblioteca
- [ ] Shared Component
- [ ] External Integration
## Interfaces
### API REST
```
POST /api/v1/users/{user_id}/change-password
Authorization: Bearer <token>
Input: {
"current_password": string,
"new_password": string,
"confirm_password": string
}
Output: { "success": true, "message": "Contraseña actualizada" }
Errors:
- 400: Validation errors (password too weak, mismatch)
- 401: Current password incorrect
- 403: Not owner
- 404: User not found
```
## Dependencias

| Longitud mínima | 8 caracteres | "La contraseña debe tener al menos 8 caracteres" |
| Longitud máxima | 128 caracteres | "La contraseña debe tener máximo 128 caracteres" |

| Minúsculas | Al menos 1 | "La contraseña debe contener al menos una minúscula" |
| Números | Al menos 1 | "La contraseña debe contener al menos un número" |
| Caracteres especiales | Al menos 1 | "La contraseña debe contener al menos un carácter especial (!@#$%^&*...)" |
| No usar password anterior | Diferente | "La nueva contraseña no puede ser igual a la anterior" |
## Límites
### Alcance
- ✅ Cambio de contraseña con validación
- ✅ Requisitos de seguridad
- ✅ Invalidación de sesiones
- ❌ NO maneja recuperación de contraseña (ver ForgotPasswordService)
- ❌ NO maneja reset forzado por admin (ver AdminService)
### Constraints
- Rate limit: 5 intentos por hora por usuario
- Timeout máximo: 1 segundo
- Máximo 3 passwords válidas en historial (evitar reutilización inmediata)
## Criterios de éxito

|----------|---------|--------|
| Disponibilidad | uptime | 99.9% |
| Latencia | p99 change_password | < 500ms |
| Rate limit | blocked attempts | 100% |
| Sesiones invalidées | después de cambio | 100% |

## Seguridad
- **Password hashing**: bcrypt, cost 12 (nuevo), verificar contra hash existente
- **Timing attack prevention**: usar constant-time comparison
- **Rate limiting**: 5 req/hour por user_id
- **Sesiones**: invalidar TODAS las sesiones del usuario tras cambio
- **Logs**: NO registrar passwords, solo intentos fallidos (user_id anonymized)
## Observabilidad
- Metrics: `password_change_total`, `password_change_failed`, `password_change_latency`
- Logs: structured JSON con request_id
- Traces: OpenTelemetry span por request

# SessionStore Component
## Purpose
Manage active user sessions in Redis for fast authentication and revocation.
## Public API
### Methods
#### create_session(user_id: str, token_id: str, metadata: dict) -> bool
Store a new active session.
**Parameters:**
- `user_id`: User identifier
- `token_id`: JWT jti (unique token ID)
- `metadata`: Optional data (IP, user agent, device)
**Returns:** True if created
#### get_session(token_id: str) -> Session | None
Retrieve active session info.
**Parameters:**
- `token_id`: JWT jti
**Returns:** Session object or None if expired/revoked
#### revoke_session(token_id: str) -> bool
Invalidate a specific session.
**Parameters:**
- `token_id`: JWT jti
**Returns:** True if revoked
#### revoke_all_user_sessions(user_id: str) -> int
Invalidate all sessions for a user.
**Parameters:**
- `user_id`: User identifier
**Returns:** Count of sessions revoked
#### get_user_session_count(user_id: str) -> int
Count active sessions for a user.
**Parameters:**
- `user_id`: User identifier
**Returns:** Number of active sessions
---
## Redis Keys Structure
```
session:{user_id}:{token_id} -> JSON session metadata
user_sessions:{user_id} -> SET of active token_ids
rate_limit:login:{ip} -> COUNT with TTL
```
## TTL
- Session tokens: 15 minutes (synced with access token)
- Rate limit counters: 15 minutes
## Dependencies
- Redis connection (via aioredis)
- TokenService (for token ID generation)
## Configuration
```python
SESSION_TTL = 900 # 15 minutes
MAX_SESSIONS_PER_USER = 10
RATE_LIMIT_WINDOW = 900 # 15 minutes

"role": user.role,
"iat": current_timestamp,
"exp": current_timestamp + 900, # 15 min
"jti": uuid4()
}
```
#### create_refresh_token(user: User) -> str
Generate a new refresh token.
**Returns:** JWT refresh token (7 day expiration)

---
## Configuration
```python
ACCESS_TOKEN_EXPIRE = 900 # 15 minutes
REFRESH_TOKEN_EXPIRE = 604800 # 7 days
ALGORITHM = "HS256" # or RS256 with key pair
SECRET_KEY = os.getenv("JWT_SECRET")
```
## Security
- Tokens include unique `jti` claim for revocation tracking
- Short access token duration minimizes theft window
- Refresh tokens stored in Redis for fast revocation
