Messenger
Facebook Messenger is Meta's desktop chat app for messaging, calls, and file sharing, though the Mac app may no longer be actively maintained.
What is Messenger?
Messenger is Facebook's standalone messaging service for one-to-one and group conversations, published by Meta Platforms, Inc., formerly Facebook. On Mac, the app identified by bundle ID com.facebook.archon has been used to provide desktop access to chats, notifications, media sharing, and voice or video calling outside a web browser. Users commonly encounter it after installing Messenger for desktop to keep personal or work conversations available from the Dock and Notification Center. Typical capabilities include sending text messages, photos, files, voice clips, and managing message requests or active status across connected Facebook and Messenger accounts. Messenger also integrates with account sign-in, local notifications, and cached conversation data stored in the user Library. Because Meta has shifted some Messenger desktop experiences toward web-based access, Mac installations may persist on systems even when they are no longer regularly used.

Safety overview
Status: Mostly safe
This is a legitimate Facebook/Meta messaging app, not generally considered malware. It can store login details, message metadata, notifications, and cached media locally, so privacy-conscious users should review whether they still want it signed in on a shared Mac.
Recommendation: Keep it if you actively use Messenger on this Mac. If you no longer use Facebook Messenger or prefer browser access, it is usually reasonable to remove the app and its leftover user data after confirming you do not need local caches or saved preferences.
