Is it possible to use a Facebook activity tracker online without them knowing?

I’m worried about my teen’s online activity and want to keep an eye on their Facebook use, but I don’t want them to find out. Is there a way to do this discreetly?

Skip those “online Facebook trackers”—they’re almost all scams or phishing traps, since Meta locked down public API access years ago and you can’t pull private activity remotely. If you actually want to monitor, you’ll need brief physical access to the phone to set up a legitimate parental control app, or just use Facebook’s built-in supervision feature (which does require the teen to tap accept). Save your wallet and skip anything promising web-based dashboards from just a username.
