+# Authentication Service
+
+Microservice for user authentication and authorization in the bakery forecasting platform.
+
+## Features
+
+- User registration and login
+- JWT access and refresh tokens
+- Password security validation
+- Rate limiting and login attempt tracking
+- Multi-tenant user management
+- Session management
+- Event publishing for user actions
+
+## Quick Start
+
+### Development
+
+```bash
+# Start dependencies
+docker-compose up -d auth-db redis rabbitmq
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Run migrations
+alembic upgrade head
+
+# Start service
+uvicorn app.main:app --reload --host 0.0.0.0 --port 8001
+```
+
+### With Docker
+
+```bash
+# Start everything
+docker-compose up -d
+
+# View logs
+docker-compose logs -f auth-service
+
+# Run tests
+docker-compose exec auth-service pytest
+```
+
+## API Endpoints
+
+### Authentication
+- `POST /api/v1/auth/register` - Register new user
+- `POST /api/v1/auth/login` - User login
+- `POST /api/v1/auth/refresh` - Refresh access token
+- `POST /api/v1/auth/verify` - Verify token
+- `POST /api/v1/auth/logout` - Logout user
+
+### User Management
+- `GET /api/v1/users/me` - Get current user
+- `PUT /api/v1/users/me` - Update current user
+- `POST /api/v1/users/change-password` - Change password
+
+### Health
+- `GET /health` - Health check
+- `GET /metrics` - Prometheus metrics
+
+## Configuration
+
+Set these environment variables:
+
+```bash
+DATABASE_URL=postgresql+asyncpg://auth_user:auth_pass123@auth-db:5432/auth_db
+REDIS_URL=redis://redis:6379/0
+RABBITMQ_URL=amqp://bakery:forecast123@rabbitmq:5672/
+JWT_SECRET_KEY=your-super-secret-jwt-key
+JWT_ACCESS_TOKEN_EXPIRE_MINUTES=30
+JWT_REFRESH_TOKEN_EXPIRE_DAYS=7
+MAX_LOGIN_ATTEMPTS=5
+LOCKOUT_DURATION_MINUTES=30
+```
+
+## Testing
+
+```bash
+# Run all tests
+pytest
+
+# Run with coverage
+pytest --cov=app
+
+# Run specific test file
+pytest tests/test_auth.py -v
+```
+
+## Database Migrations
+
+```bash
+# Create migration
+alembic revision --autogenerate -m "description"
+
+# Apply migrations
+alembic upgrade head
+
+# Rollback
+alembic downgrade -1
+```
+
+## Monitoring
+
+- Health endpoint: `/health`
+- Metrics endpoint: `/metrics` (Prometheus format)
+- Logs: Structured JSON logging
+- Tracing: Request ID tracking
+
+## Security Features
+
+- Bcrypt password hashing
+- JWT tokens with expiration
+- Rate limiting on login attempts
+- Account lockout protection
+- IP and user agent tracking
+- Token revocation support
+
+## Events Published
+
+- `user.registered` - When user registers
+- `user.login` - When user logs in
+- `user.logout` - When user logs out
+- `user.password_changed` - When password changes
