Device Portal for HoloLens

Set up device portal on HoloLens

Enable Device Portal

  1. Power on your HoloLens and put on the device.
  2. Perform the Start gesture or bloom gesture for HoloLens (1st Gen) to launch the main menu.
  3. Gaze at the Settings tile and perform the tap gesture on HoloLens (1st Gen) or select it on HoloLens 2 by touching it or using a Hand ray. The Settings app will launch after you select it.
  4. Select the Update menu item.
  5. Select the For developers menu item.
  6. Enable Developer Mode.
  7. Scroll down and enable Device Portal.

Pair your device

Connect over Wi-Fi

  1. Connect your HoloLens to Wi-Fi.

  2. Look up your device's IP address. Find the IP address on the device under Settings > Network & Internet > Wi-Fi > Hardware properties. You can also ask, "Hey Cortana, what is my IP address?"

  3. From a web browser on your PC, go to https://<YOUR_HOLOLENS_IP_ADDRESS>

    • The browser will display the following message: "There's a problem with this website's security certificate". This happens because the certificate which is issued to the Device Portal is a test certificate. You can ignore this certificate error for now and proceed.

Connect over USB

  1. Install the tools to make sure you have Visual Studio Update 1 with the Windows 10 developer tools installed on your PC. This enables USB connectivity.
  2. Connect your HoloLens to your PC with a micro-USB cable for HoloLens (1st Gen) or USB-C for HoloLens 2.
  3. From a web browser on your PC, go to


If your PC is unable to find the device, try using the real network IP address of the HoloLens device, rather than

Connect to an emulator

You can also use the Device Portal with your emulator. To connect to the Device Portal, use the toolbar. Click on this icon:

  • Open Device Portal: Open the Windows Device Portal for the HoloLens OS in the emulator.

Create a Username and Password

The first time you connect to the Device Portal on your HoloLens, you will need to create a username and password.

  1. In a web browser on your PC, enter the IP address of the HoloLens. The Set up access page opens.
  2. Click or tap Request pin and look at the HoloLens display to get the generated PIN.
  3. Enter the PIN in the PIN displayed on your device textbox.
  4. Enter the user name you will use to connect to the Device Portal. It doesn't need to be a Microsoft Account (MSA) name or a domain name.
  5. Enter a password and confirm it. The password must be at least seven characters in length. It doesn't need to be an MSA or domain password.
  6. Click Pair to connect to Windows Device Portal on the HoloLens.

If you wish to change this username or password at any time, you can repeat this process by visiting the device security page by either clicking the Security link along the top right, or navigating to: https://<YOUR_HOLOLENS_IP_ADDRESS>/devicesecurity.htm.

Security certificate

If you are see a "certificate error" in your browser, you can fix it by creating a trust relationship with the device.

Each HoloLens generates a unique self-signed certificate for its SSL connection. By default, this certificate is not trusted by your PC's web browser and you may get a "certificate error". By downloading this certificate from your HoloLens (over USB or a Wi-Fi network you trust) and trusting it on your PC, you can securely connect to your device.

  1. Make sure you are on a secure network (USB or a Wi-Fi network you trust).

  2. Download this device's certificate from the "Security" page on the Device Portal.- Either click the Security link from the top right list of icons or navigate to: https://<YOUR_HOLOLENS_IP_ADDRESS>/devicesecurity.htm

  3. Install the certificate in the "Trusted Root Certification Authorities" store on your PC.- From the Windows menu, type: Manage Computer Certificates and start the applet.

    • Expand the Trusted Root Certification Authority folder.
    • Click on the Certificates folder.
    • From the Action menu, select: All Tasks > Import...
    • Complete the Certificate Import Wizard, using the certificate file you downloaded from the Device Portal.
  4. Restart the browser.

Device Portal Pages


Your Device Portal session starts at the Home page. Access other pages from the navigation bar along the left side of the home page.

The toolbar at the top of the page provides access to commonly used status and features.

  • Online: Indicates whether the device is connected to Wi-Fi.
  • Shutdown: Turns off the device.
  • Restart: Cycles power on the device.

The home page shows the following info:

  • Device Status: monitors the health of your device and reports critical errors.
  • Windows information: shows the name of the HoloLens and the currently installed version of Windows.
  • Preferences section contains the following settings:
    • IPD: Sets the interpupillary distance (IPD), which is the distance, in millimeters, between the center of the user's pupils when looking straight ahead. The setting takes effect immediately. The default value was calculated automatically when you set up your device. Valid for HoloLens (1st Gen) only, Hololens 2 computes eye position.
    • Device name: Assign a name to the HoloLens. You must reboot the device after changing this value for it to take effect. After clicking Save, a dialog will ask if you want to reboot the device immediately or reboot later.
    • Sleep settings: Sets the length of time to wait before the device goes to sleep when it's plugged in and when it's on battery.

3D View

Use the 3D View page to see how HoloLens interprets your surroundings. Navigate the view by using the mouse:

  • Rotate: left click + mouse;

  • Pan: right click + mouse;

  • Zoom: mouse scroll.

  • Tracking options: Turn on continuous visual tracking by checking Force visual tracking. Pause stops visual tracking.

  • View options: Set options on the 3D view:- Tracking: Indicates whether visual tracking is active.

  • Show floor: Displays a checkered floor plane.

  • Show frustum: Displays the view frustum.

  • Show stabilization plane: Displays the plane that HoloLens uses for stabilizing motion.

  • Show mesh: Displays the surface mapping mesh that represents your surroundings.

  • Show details: Displays hand positions, head rotation quaternions, and the device origin vector as they change in real time.

  • Full screen button: Shows the 3D View in full screen mode. Press ESC to exit full screen view.

  • Surface reconstruction: Click or tap Update to display the latest spatial mapping mesh from the device. A full pass may take some time to complete, up to a few seconds. The mesh does not update automatically in the 3D view, and you must manually click Update to get the latest mesh from the device. Click Save to save the current spatial mapping mesh as an obj file on your PC.

Mixed Reality Capture

Use the Mixed Reality Capture page to save media streams from the HoloLens.

  • Settings: Control the media streams that are captured by checking the following settings:- Holograms: Captures the holographic content in the video stream. Holograms are rendered in mono, not stereo.
