Secrets management

Credentials belong in a dedicated vault with access control, audit and rotation, not in code, images or plain environment files.

Where it shows up in real systems

  • Secrets manager

    In production: HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, Google Secret Manager
