How to Lock a Device

The device lock is a security feature provided by Hexnode MDM. Hexnode allows IT administrators to remotely lock their client’s devices so that only the employees who know the password can access the device. This helps prevent unauthorized access to the devices. This feature is supported on Android, iOS, macOS, and Windows devices.

With Hexnode, you can secure your Android device with a Device Password, and the work container in it with a Work Profile Password. Hexnode also allows you to mandate device passcode on your iOS, macOS, and Windows devices.

On Android and iOS devices, you can also set a message to be shown on the lock screen. If the device is found missing, you can lock the device, and leave a message and a phone number on the locked screen. This message and the phone number can guide the people who find the device back to its owner.

To set password on a device

  1. Login to your Hexnode portal.
  2. Navigate to Policies.
  3. Select an existing policy or create a new one by clicking on New Policy.
  4. Under the required platform section (iOS/Android/Windows/macOS), click on Passcode or Password (varies with the platform).
  5. Select the password requirements and save the policy.
  6. Associate the policy to target devices.
Notes:

  • In iOS, the end-users will get an hour to set a passcode as per the requirements. If they fail to set a passcode within that time, then the device will be locked and the users are only allowed to access the passcode configuration page.
  • For Android devices, a prompt appears on the device. Click on Continue and set the password in accordance with the configured policy.

Locking the Device Instantly

In order to initiate an instant lock, you can follow either of these methods.

Note:

A passcode should be set up on iOS devices to display a custom message on the lock screen.

Method 1

  1. Go to Manage tab.
  2. Select the device/devices that you want to lock.
  3. From Acions, select Lock Device.
  4. Provide a custom message, phone number (both are optional) to be displayed on the iOS and Android lock screen. Specify the and the System lock PIN if you are locking a Mac device.
  5. Click Continue.

Notes:

  • Custom messages and Phone number can be displayed only on Android and iOS devices.
  • System lock PIN is a 6-digit code that you configure in the Hexnode portal. This doesn’t have to be the Mac passcode.
  • You cannot lock a macOS device without specifying the System lock PIN. Users have to enter this PIN to unlock their Mac devices.

Method 2

  1. Go to Manage.
  2. Click on the device name, this will take you to the Device Summary page.

However, these two methods are the same, the only difference is the location from which the Lock Device option is accessed.
