How do I set up multi-device parental controls
My daughter has had an iPad for several years. She uses it to play games and exchanges iMessages with friends and family. I manage her device usage via Screen Time on my iPhone. From the Settings app on my iPhone, I can change Downtime settings, enable and disable the App Store, etc. I have to the iPad Screentime settings frequently, because our model is that Downtime is always on (no iPad games) except when she has permission to play games or whatever, and then I turn Downtime off from my iPhone, for a specific amount of time.
Now we are giving her an iPhone. We want the iPhone to be very locked down. No games. No Youtube. Basically just phone calls, text and iMessages, FaceTime, Maps, Camera, maybe a couple of other select apps like plant identification. No access to the App Store. I know how to choose these settings on my daughter's iPhone.
The problem is that if both devices use the same Apple ID, any time I make changes from my iPhone, those changes will take effect on all her devices. So if I turn on App Store access (so she can install or update some games on her iPad), it will also be enabled on her iPhone. This will be a mess.
I think the answer is to set up a new Apple ID for her iPhone, and add that to our family grouping. Then I could have different Screentime settings for her iPad and her iPhone, and I can change the iPad Screentime settings from my iPhone without having impact on her iPhone screen time settings.
So where's the question? The question is whether her iPhone and iPad can share the same FaceTime accounts, iMessages accounts, and ideally the same Photos iCloud account. If so, how do I set that up?
I would prefer to keep both her devices on the same Apple ID, but I don't think that's possible unless I'm willing to give up managing her Screen Time settings from my iPhone, and just manage them locally on both her devices.
Thanks for any help and insights you can give.
