# How to Configure Username Passthrough for Samsung Knox Mobile Enrollment

[Samsung Knox Mobile Enrollment (KME)](https://www.hexnode.com/mobile-device-management/help/samsung-knox-mobile-enrollment/) allows for the bulk enrollment of corporate-owned devices. To streamline this process further, Hexnode UEM supports Username Passthrough. This feature automatically pre-fills the user’s email address (User ID) during the enrollment authentication step, requiring the user to only enter their password.

This ensures that specific devices are enrolled only by the intended users, preventing unauthorized enrollment attempts.

Prerequisites & Important Notes 
------------------------------------

- **Supported Profiles**: Username Passthrough is an optional feature available only for Knox devices enrolled via an [Android Enterprise profile](https://www.hexnode.com/mobile-device-management/help/samsung-knox-mobile-enrollment/#step-1-create-an-mdm-profile).
- **Data Requirement**: You must pre-configure the **User ID** in the Samsung Knox Admin Portal before enrollment.
- **Matching Credentials**: The **User ID** entered in the Knox portal must exactly match the **user’s email address** configured in the Hexnode portal.

Step 1: Configure User IDs in Knox Admin Portal 
------------------------------------------------

You can assign User IDs individually or in bulk within the Samsung Knox console.

### Method A: Configure for a Single User

Once the Knox side is configured, initiate the enrollment from Hexnode.

1. Log in to the **Hexnode UEM** portal.
2. Navigate to **Enroll > All Enrollments > Invite > Email**.
3. Set the **Domain** to **Local**.

    1. **Single User**: Select the user from the dropdown list.
    2. **Bulk Users**: Upload a .csv file containing the user details.
5. Send the invitation.

What Happens on the Device? 
----------------------------

When the user powers on the device and begins the enrollment process:

1. The **User ID** configured in the Knox Portal is automatically passed to the Hexnode UEM app.
2. The **Username field** on the authentication screen will be pre-populated and locked (grayed out).
3. The user cannot change the username; they simply enter the password (provided in the enrollment email or their directory password) to complete setup.

Frequently Asked Questions (FAQs) 
----------------------------------

### Q1: What is Samsung Knox? 

**Samsung Knox** is a defense-grade security platform built into Samsung mobile devices from the chip up. It provides real-time protection against malicious attacks and creates a secure container to separate work data from personal data. For IT admins, it also offers a suite of cloud solutions (like Knox Mobile Enrollment) to deploy, manage, and secure devices at scale.

### Q2: Is this feature mandatory for KME? 

No, it is optional. If you leave the User ID field blank in the Knox Portal, the user will be required to manually type their username and password during enrollment.
