    Hi,

    while watching the companion device framework presentation found on MSDN, I noticed that on the slide where it describes how PC and companion device can communicate there is an icon for a QR code. I haven't worked with Windows Hello before, but have developed Credential Providers. In credential providers, displaying my own window on the lock screen was quite complicated and messy.

    I am wondering if someone has any experience with displaying UI on the lock screen from a background task registered for a companion device. I haven't been able to find an example which does this so far online. Would I be able to do it using C# and XAML, or does it require messing with C++ calls? To simplify, would I be able to show a QR code on the lock screen from a Windows Hello companion device background task?

    Thank you.

    There are numerous ways one can use the Windows Hello companion device framework to build a great Windows unlock experience with a companion device. For example, users could:

    • Attach their companion device to PC via USB, touch the button on the companion device, and automatically unlock their PC.
    • Carry a phone in their pocket that is already paired with PC over Bluetooth. Upon hitting the spacebar on their PC, their phone receives a notification. Approve it and the PC simply unlocks.
    • Tap their companion device to an NFC reader to quickly unlock their PC.
    • Wear a fitness band that has already authenticated the wearer. Upon approaching PC, and by performing a special gesture (like clapping), the PC unlocks.

    For more information and sample code, please refer to this document below.

    Besides, this forum is about developing desktop applications, for your case, I suggest you post on UWP forum for better support.

    Thank you for replying, but the quote from the msdn page you provided doesn't really relate to my question. I will try my luck on the UWP forums, thank you for directing me, I wasn't completely sure where I should post the question when I submitted it.
