As much as I think I love this feature, you are probably right. If using PIN code login on Windows, “locking” (Win+L) can be a similar replacement for additional PIN security via app. So I need to improve my habit of locking Windows. I see there is a way to set screensaver (can use “none”) to lock Windows after a number of minutes, will try.
Also, many of the Android apps (banking, etc) use the PIN code login as a “quick” login, once device is confirmed verified by user. But these apps usually log out frequently! That may actually be why I love PIN login feature. As long as AxCrypt does not frequently log out user (needing full password often), the PIN feature may not be as useful or necessary.
