PHP Requirements:

  • PHP 7.0 or later

  • JSON extension
  • OpenSSL extension

Download & Installation:

Extract the package (that you received after purchasing this plugin), copy all the files & folders, and paste them at their respective locations under the installation directory of PHPKB Knowledge Management Software on your server. There is a new folder, called ‘add-ons’ (applicable to PHPKB v9.0), copy that and put it directly under the root folder (i.e. outside /admin/ folder) of the PHPKB package.


  1. Log in to the Administrator Control Panel of PHPKB as a Superuser, go to Tools > OAuth / OpenID-Connect plugin.
  2. After successfully logging in to PHPKB (at Step 1), open a new tab/window and log in to Auth0 Dashboardas we are going to configure some of the settings parallel.
  3. Click Applications > Applications (which is available in the Left-Sidebar menu) and then click Create Application button.

    Create New Application

  4. Enter the Name of your application and select Choose an application type as Regular Web Applications and click on the Create button.

  5. Once your application has been created, it will be opened by default, select the Settings tab (next to the "Quick Start" tab), you will see the Basic Information section, and since you have already logged in to the Administrator Control Panel of PHPKB, copy the Client ID and Client Secret from this screen (Auth0 Settings), and paste them, one by one, in the Tools > OAuth > Client ID and Client Secret input boxes.

  6. Then scroll down to the Application URIs section, paste the Redirect URL (by copying from Tools > OAuth > Basic Configuration section > Redirect URL) in the Application Login URI & Allowed Callback URL input boxes.

    Set Application URIs

  7. Now, scroll down further, click on the Advanced Settings section, click on the Grant Types and make sure these are selected (especially the Authorization Code option), and update it in the Tools > OAuth > Grant Type option. (Default: Authorization Code)

    Advanced Settings - Grant Types

  8. After enabling the desired Grant Types, expand Endpoints, copy the values in fields 1, 2 & 3 (as shown in the screenshot below), and paste them in the Tools > OAuthAuthorize EndpointAccess Token EndpointGet User Info Endpoint input boxes respectively.

    Advanced Settings - Endpoints

  9. Thereafter, copy the last URL (i.e. #4 as shown in the screenshot at Step 8), open a new tab/window, and at this point, copy the issuer URL (without quotes) from the JSON data, and paste it into the Tools > OAuth > Issuer URL box.

    Endpoints - Copy Issuer URL

    Note: If you have installed any JSON Viewer extension in your browser then it would output the JSON data in a friendly & readable format, otherwise, you would see it as raw output (unformatted).

  10. Let us configure the other settings. 

    Tip: To make the configuration task easier, helpful notes/tips are added under the fields/options where it is necessary.
