This plugin provides single sign-on functionality between a WordPress site and Zendesk, designed for website administrators who want to simplify user access to their support system. It allows logged-in WordPress users to automatically authenticate into Zendesk, eliminating the need for separate credentials and improving the customer support experience.

• JWT Authentication: Uses Zendesk's official JSON Web Token endpoint for secure, industry-standard authentication without third-party services.
• Simple Setup: Configure by entering your Zendesk subdomain and shared secret, with no complex dependencies or external SDKs required.
• Lightweight Integration: Has a small footprint of around 40 KB, with no background services, telemetry, or performance overhead.
• Shortcode Implementation: Add a shortcode to any page to create an SSO login link, making it easy to integrate into menus or support sections.
• Secure Design: Based on the Firebase PHP-JWT library, generating tokens on demand with minimal user data and immediate expiration for enhanced security.
