Unrecognized logins alerts can be turned on by three methods such as native notifications from your device or browser, messenger alerts and email notifications.
Facebook may stop sending messenger login alerts for unrecognized logins. Yesterday, most facebook users received the message “Messenger alerts about unrecognized logins into your account are disabled”. Some users confused because their messenger alerts are still turned on. And they worried about their account security.
Some users still have the option to turn on the messenger alerts for unknown logins but that option is completely disappeared for some users. It is not sure that messenger login alerts will be removed permanently or not.
