Beskrivelse
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.

FAQ
-
Is this plugin free?
-
Yes. 100% free. As in free beer. No pro version. No nagware.
-
Is this plugin lightweight?
-
Yes. It loads ~40kb of code when it runs.
-
Does this plugin require any other plugin?
-
No. This is a standalone plugin and does not depend on any other plugin.
-
Does it work with modern Zendesk accounts?
-
Yes. It implements the standard JWT-based SSO endpoint (
/access/jwt). -
Is Composer required?
-
No. The JWT library is bundled directly in the plugin for convenience and meets WordPress PHPCS standards.
-
Does this plugin store any user data?
-
No. It simply authenticates the current logged-in WordPress user and securely passes their name and email to Zendesk for SSO. No personal data is logged or retained by the plugin.
-
Can I customize the login redirect page?
-
Yes. You can set a custom login page under Settings Zendesk SSO Login Redirect Page.
If left blank, it defaults to the standard WordPress login screen. -
Does this plugin support multisite installations?
-
Yes. It can be network-activated or activated on individual subsites. Each site can have its own Zendesk configuration.
-
Can this be used with caching or security plugins?
-
Yes. It’s compatible with common caching and security plugins.
If your caching plugin caches logged-in pages, exclude the page containing[tokenlink_zendesk_login]to ensure proper redirects. -
Will it conflict with existing SSO or login plugins?
-
No, it runs independently. It only triggers when the
[tokenlink_zendesk_login]shortcode is executed, so it won’t interfere with other authentication systems. -
Does this plugin work with Cloudflare or reverse proxies?
-
Yes. As long as HTTPS and PHP sessions function normally, JWT SSO works over any proxy or CDN.
-
I’m getting a 502 or redirect loop. What should I check?
-
Verify your Zendesk subdomain and shared secret are correct, and that your Zendesk SSO settings point to your WordPress page URL containing
[tokenlink_zendesk_login].
