 > [!WARNING]
 > \*When the server is configured to use MATLAB Runtime versions prior to R2023b, the `unsafe-inline` attribute is set in the `script-src` directive of the server's Content Security Policy on the server and cannot be removed. The attribute allows inline JavaScript execution and event handlers contained within a web app to execute on the server. These runtimes are disabled by default starting in R2024b. You can enable them using the [webapps-runtime](https://www.mathworks.com/help/webappserver/ref/webappsruntime.html) command.

 1. During the registration process, you need a redirect URL for MATLAB Web App Server. The format of the URL is: `https://<MATLABWebAppServer_hostname>:<port_server_is_running_on>/webapps/extauth/callback`. For example: `https://example.com:9988/webapps/extauth/callback`.
 1. Create a file named `webapps_authn.json` using the JSON schema specified [here](https://www.mathworks.com/help/webappserver/ug/authentication.html#mw_908077ba-725e-4cc9-a906-a1bf29fceaf8) and place it in the `webapps_private` folder of the server. For folder location, see the [doc](https://www.mathworks.com/help/webappserver/ug/authentication.html#mw_146e67b0-5dff-4310-8d5d-544250e931a9).
 1. To place the `webapps_authn.json` file in the `webapps_private` folder of the server, you need to remotely connect to the server using RDP on Windows or SCP on Linux. Once connected, you can drag-and-drop the `webapps_authn.json` file you created into the `webapps_private` folder of the server. Alternatively, you can drop the file into the file share first, before moving it to the `webapps_private` folder.
