Is it possible to see WhatsApp messages from another number remotely?

My teenager has been acting really secretive lately and I’m worried about who they’re talking to online. I’ve looked into a few parental control apps but most only work if you already have physical access to their phone. Is there any legitimate way to monitor their chats remotely, or do I absolutely need to install something on their device first?

Kid’s safety is the top priority, no need to overthink it. You can use built-in OS tools like iCloud or Google Family Link to monitor their activity, but for WhatsApp specifically, I’d recommend mSpy for remote monitoring - it’s a solid solution that gets the job done without the drama.
