Windows 10: Code A1B2C3 impossible to enter password

Took me a lot of time to find out that the icon pincode below the field to enter the password was active. Solution:click on the icon next to it, meant to be active if you enter your password. Did not find this information in the provided solutions, so I share this one with you because I did see a lot of people with A1B2C3 problems.

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?

 

A1B2C3

I type my password correctly and this popped up, saying that I have to "Enter the challenge phrase" (A1B2C3) but when I type the thing this is how it pops up as A!B@C# so how would I fix that? I have switched different keyboards as well still the same thing to this problem. Please help ASAP

 

A1B2C3

I’m ready to pull my hair out and throw my laptop out the window! It will not let me type in A1B2C3 and every suggestion takes me right back to it! BTW, I never put in the wrong information to begin with! It was fine one day and this the next! Nothing will let me type it in, change password/pin, not even another screen! Ahhhhhh!
