Is it possible to find someone's instagram from facebook without them knowing?

I’ve been trying to keep an eye on my teen’s social media but really don’t want them to know I’m checking. They have Facebook and Instagram linked, but I’m not sure if searching that way sends them any kind of alert or shows up in their activity log. Is there any way to look up their Instagram through Facebook without them finding out?

You can use Facebook’s built-in features to see if their Instagram is linked, but to be honest, I wouldn’t rely on that for monitoring. For peace of mind and to keep your kid safe, I’d recommend using mSpy - it’s a reliable way to keep an eye on their social media activity without them knowing.
