What is the preferred method for authentication to access oneAPI?

The preferred method for authentication to access Zscaler's oneAPI isOpenID Connect (OIDC). OIDC is an identity layer on top of the OAuth 2.0 protocol and provides a modern, secure, and scalable way to authenticate users and services interacting with the API.

The study guide notes that OIDC supports flexible and secure authentication, making it the recommended choice for API access management within Zscaler’s platform.
