# Enabling Single Sign-On (SSO) for Employees
To allow employees to use the SSO service, follow these steps:
### **1. Order Licenses**
Ensure that you have an active [license](/hideez-enterprise-server/single-sign-on-settings/how-to-get-employee-licenses.md) for each employee who needs access to the Hideez Enterprise Server (HES) and SSO functionality.
### **2. Assign SSO Permissions**
By default, employee accounts do not have access to the SSO service. This access must be explicitly granted by an administrator.\
You can [enable](/hideez-enterprise-server/employees/how-to-add-an-employee.md#the-single-sign-on-page-optional) SSO either when creating a new employee or by editing an existing one:
* **For New Employees**: Enable the "Enable SSO" option during the employee creation process.
* **For Existing Employees**:
* Go to the **Employees** section.
* Select the employee.
* Click **Edit**.
* On the opened page, click the **Enable SSO** button to grant access.
### **3. Enable Authentication Methods**
* To enable passwordless authentication, check the **"Passwordless Authentication"** checkbox.
* To enable two-factor authentication (2FA), check the **"Use Two-Factor Authentication"** checkbox.

**NoNote:** A valid email address is required to activate SSO for the employee.
{% endhint %}
### Advanced Settings
If **External ID** is used as the **Name Identifier Field** in your SAML configuration, you must manually populate the External ID for each employee.
To do this:
1. Go to **Employees**.
2. Select an employee.
3. Click **Details**.
4. Navigate to the **Single Sign-On** section.
5. Click **Edit settings**.
6. Enter the **External ID** value and save the changes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://enterprise.hideez.com/hideez-enterprise-server/single-sign-on-settings/nastroika-polzovatelei.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
