# Default Credentials

## Overview
Default credentials are pre-configured usernames and passwords that ship with software, databases, or infrastructure components. Attackers maintain databases of default credentials and routinely attempt them. Common examples:
- `admin:admin`, `admin:password`, `root:root`
- Database defaults: `mysql root:""`, `postgres postgres:postgres`
- IoT/Router defaults: `admin:1234`, `admin:admin`

## Remediation
- Change all default credentials immediately upon installation
- Enforce strong, unique passwords for administrative accounts
- Use secrets management systems for credentials in code
- Detect default credentials in CI/CD pipelines
