Windows 10: Required to type 'A1B2C3' before entering PIN

As of a week ago, I have been receiving the error message, "You've entered an incorrect PIN serveral times. To try again enter A1B2C3 below." The problem with that is that I have never entered my PIN incorrectly and am the only one that utilizes my desktop. I have ran malware/virus scans and have turned up zero discrepancies. Additionally, I reinstalled Windows 10 (and activated) a month ago after upgrading my motherboard, processor, and memory. So why is it asking me to enter in this letter/number combination EVERY time despite never having entered in my PIN incorrectly? This is rather annoying and essentially a two-step authentication factor, of sorts, that I did not ask for. Is anyone else experiencing this?

"You have entered an incorrect pin several times" message when I turn on the PC

Hi,

Quite often, when I start my PC, at the login screen I get the message "you have entered an incorrect pin several times", which is of course not the case, since I just turned on the machine.

At that point, I have to type A1B2C3 to unlock the prompt and enter my pin.

Is there a way to fix this?

Thanks.
