# Generate a Custom Server Token

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.

> **Info :** Refer to the [SDK Scopes table](https://docs.catalyst.zoho.com/en/sdk/python/v1/sdk-scopes) to determine the required permission level for performing the below operation.

**Parameters Used**

<table class="content-table">
	<thead>
		<tr>
			<th class="w20p">Parameter Name</th>
      <th class="w20p">String</th>
      <th class="w60p">Definition</th>
		</tr>
	</thead>
	<tbody>
		<tr>
			<td>`type`</td>
      <td>String</td>
			<td>A **Mandatory** parameter. Will hold the value of the application type.</td>
		</tr>
    <tr>
			<td>`user_details`</td>
      <td>Object</td>
			<td>A **Mandatory** parameter. Will hold values of first_name and email_id of the end user.</td>
		</tr>
	</tbody>
</table>

**Package Imports**

```java
import zcatalyst_sdk
```

```python
def handler(context, basicio):
    app = zcatalyst_sdk.initialize()
    auth = app.authentication()
    resp = auth.generate_custom_token(
        {
            "type": "web",
            "user_details": {
                "first_name": "Amelia",
                "email_id": "amelia.burrows@zylker.com",
            },
        }
    )
    basicio.write(str(resp))
    context.close()
```

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.
