# User and Machine Identities

> Learn more about identities to interact with resources in Infisical.

To interact with secrets and resource with Infisical, it is important to undrestand the concept of identities.
Identities can be of two types:

* **People** (e.g., developers, platform engineers, administrators)
* **Machines** (e.g., machine entities for managing secrets in CI/CD pipelines, production applications, and more)

Both people and machines are able to utilize corresponding clients (e.g., Dashboard UI, CLI, SDKs, API, Kubernetes Operator) together with allowed authentication methods (e.g., email & password, SAML SSO, LDAP, OIDC, Universal Auth).
