Ok, this has been working, although a bit of a hit-n-miss sometimes for the screens we have in the office, Philips Brilliance 499P, which have Windows Hello compatible cameras. Most often if I boot my laptop at work and start it with the lid closed the external camera on the 499P will log me in.

 

However, if I at some point during the day open the lid on the laptop (Dell XPS 17, also with Windows Hello camera), it stops working on the external screen and only the laptop camera will log me in (which is annoying as I have the laptop on a shelf underneath the table).

 

I recently got a Logitech BRIO 4K with Windows Hello for my home office but that is even harder to get working with Windows Hello. The camera works fine, and if I chose to "improve my face recognition" Windows happily is using the Logitech BRIO cam and not the Laptop one.

 

If I boot my laptop at home with the lid closed the Logitech BRIO logs me in the first time, but if I lock my computer, or it goes to sleep over lunch, the Logitech BRIO isn't working anymore (Windows Hello says it can't find the device) but logging in with password and checking the device manager the camera is there and working. Also, opening the lid of the laptop instead of giving the password also logs me in, so clearly Windows has chosen to use the laptop cam and disabled the external one (even though the lid has been closed all the time).

 

I found a post to set the Registry Key "Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\LidNotifyReliable" to 0 (zero) and that seems to help getting the external camera enabled for Hello again, but again, just once... Locking the computer and trying Hello again, and it won't work...

 

I've also seen a number of posts saying to "set a default camera" in devices and printers but that option hasn't been there since Windows 8 I think so that is not a helpful answer...

 

Let me try and summarize my issue real short:

- Windows Hello works every time when I am using the laptop camera only

- Hooking up the Philips 499P screen camera or Logitech BRIO 4k (both over USB-C/Thunderbolt) it most often works to use any of those cameras once after being hooked up after closing my lid on the laptop.

- After successfully using the external camera once, and then try to use it again it normally fails with a message it couldn't use the camera and I should use another method of signing in.

- If I open the laptop lid after it has failed the laptop camera works and logs me in.

 

So, it's like Windows Hello is losing the "connection" to the external camera but it can still find and use the laptop camera.

 

Windows Version and Edition?

Version 21H2 (22000.376)

Windows 11 Business

 

I had thought that since Windows 11 Hello would support multiple cameras... :(
