TokenLink SSO Login for Zendesk

TokenLink SSO Login for Zendesk allows WordPress site administrators to provide seamless, secure single sign-on (SSO) access to Zendesk using JWT (JSON Web Tokens) authentication.

This plugin uses the official Firebase PHP-JWT library (BSD 3-Clause licensed, included and updated for WordPress compliance).

Setup takes less than five minutes using standard WordPress shortcodes — no third-party dependencies, no tracking, no bloat.
