Security certificate

Modified on Fri, 3 Jun, 2022 at 2:38 PM

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


Each HoloLens generates a 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". You can securely connect to your device by downloading this certificate from your HoloLens over USB or a Wi-Fi network you trust and trusting it on your PC.


  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.
    • Navigate to: https://<YOUR_HOLOLENS_IP_ADDRESS>/devicepair.htm

    • Open the node for System > Preferences.

    • Scroll down to Device Security, select the "Download this device's certificate" button.

  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.

    • Select 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.
