Understanding JWT in Zendesk SSO

Learn how JSON Web Tokens (JWT) are used for secure single sign-on (SSO) in Zendesk.

What is a JSON Web Token (JWT) and how is it used in Zendesk SSO?

A JSON Web Token (JWT) is a technology used for single sign-on (SSO) authentication in Zendesk. It allows Zendesk to trust login requests from your systems. JWTs are not placed directly in URLs due to security concerns. Instead, they are generated server-side and passed as a parameter in the query string to a Zendesk-specific URL. This ensures secure authentication by verifying the JWT's signature using a shared secret.Learn more about JWT in Zendesk SSO.
