What is a key feature of OpenID Connect (OIDC)-based authentication for users?

Comprehensive and Detailed 100 to 150 words of Explanation From Zscaler Digital Transformation Administrator topics:

OpenID Connect is an identity layer built on OAuth 2.0 and commonly represents identity information in JSON Web Tokens (JWTs), making C correct. A signed ID token carries claims about the authenticated user and can be validated by the relying service using the issuer’s published keys. This JSON-based design distinguishes OIDC from SAML, which normally represents assertions in XML. OIDC does not inherently require annual certificate maintenance; signing keys and validation metadata are managed through the provider’s configuration and key-discovery mechanisms. Attribute-based access control can consume identity claims, but it is not the protocol characteristic being tested. Zscaler’s administrator study material identifies JWTs as JSON-based tokens used in OIDC contexts, and its OpenID configuration documentation explains that attributes are obtained from the OIDC JSON.
