Screen time password not required to extend limit

I used to use screen time as a way to force myself to not use some apps too much. I asked my roommate to set up a password and not tell me, and I would ask her for it only in emergencies. It worked pretty well, but since a few months ago screen time is no longer prompting me to put a password if I click on ‘allow 15 more minutes’ once the app limits have been exceeded. I have heard that it works if it on a child’s device, but I can’t pretend my phone is my child’s device because it asks for a different Apple ID to set up screen time than the one on the device. Is it normal that it no longer asks for a password if you are setting the screen time on your own device? If so, what is even the point of having the ability of setting up a password in this case?
