MessengerLoginHelper
MessengerLoginHelper is a Messenger background login item that launches helper components when you sign in to macOS.
What is MessengerLoginHelper?
MessengerLoginHelper is a macOS login item installed with Messenger. It is stored inside the Messenger app bundle and runs in the background when you log in to your Mac so Messenger can start supporting app functions without requiring you to launch every component manually. Users typically encounter it in Login Items or Background Items settings rather than opening it directly. In normal use, this kind of helper supports desktop messaging workflows such as faster app startup, background readiness for chats, and delivery of message or call notifications. It is part of the Messenger desktop app environment for people who use Messenger on macOS.

Safety overview
Status: Mostly safe
A login helper inside /Applications/Messenger.app is consistent with Messenger's desktop app behavior on macOS. Because it launches at sign-in, it can keep parts of Messenger active in the background for notifications and related app functions. Check that the parent app is the Messenger app you intentionally installed and that macOS shows it as a Messenger-related background item. If you no longer use Messenger, this item does not need to stay enabled.
Recommendation: Keep this item enabled if you want Messenger available more quickly after login or you rely on desktop notifications and call alerts. If you do not use Messenger on this Mac, you can disable the login item to reduce background activity; Messenger may open more slowly or miss background notifications until you launch the app.
