# Generate a Custom Server Token

> **Note:** This SDK is currently in deprecation. Migrate to [JavaScript SDK](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/overview/) now.

Cloud Scale's Authentication component allows you to implement a [third-party authentication service](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/third-party-authentication/introduction/) of your preference for your Catalyst application. The authorization and validation of the end-user is handled by the third-party service, and the data is passed on to Catalyst. 

> **Note:** 

* Since you are implementing a third-party authentication service, it is understood that the security infrastructure of your application is contingent on the efficiency of the third-party service that you have chosen.
* To enable a third-party authentication in your Catalyst application, you must ensure that you have enabled [Public Signup](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/public-signup/) in the console.

When a user is re-directed from a third-party service after being authenticated, their credentials must be passed to an authentication function that you code. This function must include the Catalyst server-side script to generate a custom server token, which will then be passed to the Web SDK incorporated in the client code.

```javascript
const userManagement = catalystApp.userManagement();
userManagement.generateCustomToken({
  type:'web',
  user_details:{
   email_id: "${email_id}",
   first_name: "${first_name}",
   last_name: "${last_name}",
   org_id: "${org_id}",
   phone_number: "${phone_number}",
   country_code: "${country_code}",
   role_name: "${role_name}"
  }
});
```

You can now pass this token to the client logic as explained in this [Web SDK help page](https://docs.catalyst.zoho.com/en/sdk/web/v4/cloud-scale/authentication/third-party-custom-token/).

> **Note :** The custom server token will have to be generated every single time the user logs in to your application using a third-party authentication service.
