# User Guide

{% hint style="info" %}
All users entering environments where mobile devices are not allowed must complete fingerprint enrollment to authenticate their Active Directory account.
{% endhint %}

***

### Steps to Enroll

#### Step 1: Open ThinC Manager

After completing the standard Windows logon (username and password), click the **Start** button, search for **ThinC Manager**, and open the application.

#### Step 2: Sign in

Enter your Active Directory account (network ID) and password, then click **Submit**.

Allow a few seconds for validation to complete.

#### Step 3: Enroll your fingerprint

The **Device Management** module appears by default.

1. Select **Add Another** under the finger section.
2. When the pop-up appears, look at the fingerprint reader.
3. When the device starts blinking, provide the fingerprint of your desired finger.
4. Keep pressing with different parts of the finger until the capture reaches 100 percent.

Repeat to add additional fingers as needed.

{% hint style="warning" %}
If registration does not complete successfully, contact your administrator.
{% endhint %}

#### Step 4: Add the security key

1. Navigate to the **Account Management** module.
2. Click **Add Security Key**.
3. Provide the already-enrolled fingerprint on the device to complete the process.

When the required fingerprint is provided, a **Device Registration** successful message appears.

### Authentication

{% hint style="info" %}
The machine and fingerprint reader you authenticate with can be different from the ones you used to enroll. Any machine with any connected 1Key device can authenticate you.
{% endhint %}

#### Steps to Authentication

#### Step 1: Select the key login option

At the Windows logon screen, select the **login with key** icon in the bottom-left corner.

#### Step 2: Enter your user ID

Enter your user ID in the logon field, then click the **→** arrow next to the user ID field. Wait for the next screen to load.

#### Step 3: Provide your fingerprint

When the screen asks you to touch the key, provide your enrolled fingerprint when the device lights up.

{% hint style="warning" %}
If the login fails, contact your administrator.
{% endhint %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.1kosmos.com/authentication/1key-biometric/user-guide.md?ask=<question>&goal=<endgoal>
```

`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.
