Circumventing a Screen Time passcode by performing an Emergency Reset (Settings | Privacy & Security | Safety Check) is an intriguing idea. But, if this worked, wouldn’t a child use it to easily bypass the Screen Time restrictions placed on an iPhone by their parents? I have not seen reports that such is the case, which causes me to question the concept.
The Apple documentation only says “If your iPhone has Screen Time restrictions turned on or has a mobile device management (MDM) profile installed, you can still use Safety Check, but some functionality may not be available.” I do not see any indication in the documentation that Safety Check (Emergency Reset) disables the Screen Time passcode. In addition, although emergency contacts can be updated, there is no mention that recovery contacts can be changed by using Emergency Reset.
Yet, I recognize could certainly be mistaken, and look forward to hearing more about this possibility from the community….
My daughter and granddaughter have iPhones and set up as parent and child. The passcode for the child phone is different than the passcode for the parent device. Cannot unlock with this on the child’s phone but you can on the parent device.
So the kid is better protected tab mom or dad.
