Honestly, most “remote” Facebook monitoring tools are hit-or-miss, but mSpy is the one that actually delivers on Messenger chats—it pulls message logs, timestamps, and contact info straight from the target device to your dashboard. The catch is you’ll need initial physical access to set it up, and some media files in chats don’t always sync perfectly. TL;DR: if you want simple, use built-in Family Link for basics, if you want deep data including Messenger, use mSpy.
