I've searched around about Windows 10 PINs and although have seen a few answers regarding the security of them as a whole, I haven't found any discussing the fact that when I type in my PIN, the desktop will begin logging in without me ever hitting enter. Assuming PIN is enabled for login, what's stopping someone from using something like the USB rubber Ducky and cycling through all possible number combinations up to, say 15 digits. Since there is no part where the user needs to hit "enter", incorrect PINs wouldn't have a chance to be counted and locked out.
From the sound of this, it seems a Windows 10 computer could be broken into relatively quickly brute-forcing the PIN. Is it really this easy or am I missing something? Is a having a Windows 10 pin really a safe option?
EDIT: I have done some testing around my question. So far, manually typing in incorrect PINs, deleting them if Windows doesn't automatically log in, and trying a new one has not caused a lock-out of any sort. If I type in an incorrect PIN and hit ENTER multiple times, I will eventually reach an "are you not a robot" screen. If I never hit ENTER it seems I won't see that screen (so far). I will continue testing and creating a script.
