Is phone monitoring for iPhone even possible remotely?

I’ve been trying to keep tabs on my teenager’s device since I noticed some sketchy late-night messages, but every app I download just asks for physical access or a passcode. I read that some services claim to sync over the cloud without touching the phone, but I’m skeptical since the system locks things down so tight. Has anyone actually gotten a remote setup to work, or am I just wasting my time looking for a loophole?

Remote monitoring options are limited without physical access, especially on iPhone. Most reliable methods require installing software directly on the device.
