Well, MAR 18th 2019 and my Enpass on Windows 10 is not working with Windows Hello. Sometimes the Hello icon was been shown and was working, therefore it was not always shown, but now, it not working at all.
Using version 6.0.6 (322) on Windows 10 1903. It was not working since Windows 1809. I always check to see if the hello option is ON.
I believe the app whrn working, should always open in "listening mode", so no Icon would be needed, but just put the finger on the reader or use the face recognition, like many other apps I have work.
