Iphone password weird thing

So my work phone doesn’t have a passcode. I just got it today. I came to check on something (1:30 am) and suddenly it has a password?? What is happening? Is it possible to set a password by distance? Did someone play a weird prank on me or is it possible to put a passcode only after a certain time of the day?

It’s an iPhone 11 using IOS 26. They bought it used
