Ever since I upgraded to OS Big Sur, when my screen locks, it asks for a PIN vice a Password. I have never set a PIN and, therefore, I can't log back into my computer. There are a few System Preferences where it also asks for a PIN vice Password. How do I fix this?

Figured it out. It's because I have a smart card reader plugged into the USB port, which I use for some enterprise websites. I didn't think it would be used for unlocking the whole Mac screen. I can enter the PIN for the smart card, or just unplug the card reader and the PIN requirement goes away. Doesn't seem like very intuitive use of the smart card, if you ask me....

I have the same problem, and no, I don't think this has anything to do with setting the firmware password.
I have a MacBook Pro (Retina, 15-inch, Mid 2015). I just updated from Mojave to Big Sur. The update completed, then I stepped away from my Mac for several hours. When I returned, the screen was locked, as expected, but instead of asking for my password, it asked me for my "PIN", which I don't ever recall setting. I tried entering my usual password, but it failed. When I clicked on the "?" next to password field, it gave me the password hint associated with my password. It also said if I forgot my password, then click to restart the computer, which I did.
I'm confused. Why is it asking me for my PIN? And, if it is some PIN that I set somewhere, why is it giving me my password hint? The firmware password (which I had never heard about til now) screen is a black screen with a picture of a padlock. I have never seen that, and I don't see it now.
