I've been using 10 since the first week it was officially released. Updated from 8.1 Home.
When I need to access settings that require admin rights, the user account control box always comes up and asks for the admin password. Today when accessed, it suddenly started giving the option to enter password *or PIN*. This has never happened before. I've never used the PIN for anything and don't exactly remember even setting it up, however, when I typed what I thought it *would* be if I had set it up - it was correct.
What would make Windows 10 suddenly start giving the second option to enter PIN when it never had before?
Should I be worried that someone tried to (or did) access my computer while I was away?
Did I just fall for a password/PIN hack of some kind? It's happened before.
EDITED TO ADD:
I just noticed that under settings/accounts/sign in options that it indicates I do NOT have a PIN set up already. It only gives me the option to add one. Not to change or remove.
