How can I improve Screen Time management for my child?

Turns out: you are right! It would appear my son knew the code. That is why I always saw “Screen Time Unlock” in his list of activity when he bypassed the screen time. It’s not a kind of App or anything: he was just typing the code. I changed the code again, and this time I made sure to never enter the code on his iPad (he needs to send me a request that I accept on my phone). Since then, he has not bypassed the screen time. Good to know: when I modify the screen time code on my phone, it does not immediately change on his iPad, there is a certain delay.

So I guess he must have found a website that allowed a screen recording on which the code was visible. In his deleted photos folder, I found a video recorded from his screen while someone was typing the code. It was not visible on that video, but I guess he found a screen recorder on which it worked and made sure to delete that one, or perhaps the video stayed in a Projects folder in an account he created on the website or App (and did not appear in his Photos folders). I deleted all suspicious Apps on his iPad (like CapCut and VideoLeap); anything he did not need for school according to the list provided by the school. I made sure the settings do not allow him to install any App without my approval. I also restricted his access to websites: he can now only access a limited list of websites (needed for school) that I listed one by one myself. Tidious job, all that!

Hope this helps other parents.

Apple: I don’t think it’s safe to have one code that allows to modify anything and everything in the parental control. It should be one code to give extra screen time, and another code to change the settings.
