To enhance security on Facebook, users can implement measures such as enabling two-factor authentication (2FA) to add an extra layer of protection beyond passwords. Regularly reviewing and adjusting privacy settings is crucial, controlling the visibility of personal information and limiting the audience for posts. Additionally, staying vigilant against phishing attempts, recognizing and avoiding suspicious links or messages, contributes to a more secure online presence. Keeping the account information updated and periodically reviewing login activity through Facebook's security settings ensures proactive monitoring for any unauthorized access.
