What security feature can Facebook users enable to alert them of possible hacking attempts on their account?

The correct choice, which is login alerts, is a security feature designed to notify users whenever there is an attempt to access their account from an unrecognized device or location. This feature enhances security by providing real-time notifications, allowing users to take immediate action if they suspect unauthorized access. By enabling login alerts, users can monitor their accounts more effectively and respond quickly to potential threats, ultimately reinforcing the security of their Facebook accounts.

While privacy settings play a crucial role in controlling who can see a user's information and posts, they do not provide alerts about hacking attempts. Two-factor authentication enhances security by requiring a second form of verification during login, making it more difficult for a hacker to access an account; however, it does not provide alerts about potential unauthorized access. Account review helps users assess their security posture but does not alert them to real-time hacking attempts. Thus, login alerts specifically address the need to be informed about unauthorized access.
