Machine Credentials

Machine credentials are cryptographic artifacts used to authenticate and authorize non-human identities (NHIs) — including passwords, API keys, certificates, tokens, and SSH keys used by applications, services, and automated processes.

❓ What is Machine Credentials?

⚙️ How Does It Work?

Machine credentials are stored in secrets managers or PAM vaults, rotated regularly, scoped to least privilege, and monitored for anomalous usage. Unlike human credentials, they are never entered manually — they are injected programmatically.

📍 Where Is It Used?

Any application, script, CI/CD pipeline, cloud workload, or automated process that needs to authenticate to another system.

💡 Real-World Example

A DevOps team has 300 microservices, each requiring credentials to access databases, message queues, and APIs. Without a secrets manager, credentials are scattered in config files and environment variables. With HashiCorp Vault, each service retrieves short-lived dynamic credentials at runtime — no static secrets anywhere.
