Screen Time Passcode Randomly Set?

Hey,

I have recently downloaded macOS Catalina and I was excited because I heard it was supposed to improve battery life. While I was scrolling through my settings, I noticed something called Screen Time. I've heard that this app was on phones but I guess it was just added to macs. I went in and I wanted to disable Screen Time. Then, I was prompted to enter a passcode. During setup, I had chose not to enter any passcode or use Screen Time? Did it set a random passcode, or is there a default one? I want to remove the passcode entirely but I can't figure it out! Please help.

Thanks!
