In an era of escalating online threats, enabling two-factor authentication (2FA) on Facebook and Instagram is crucial for protecting accounts. This security feature requires users to verify their identity through a password and an additional method, such as a text message or authentication app. Users can easily activate 2FA on both platforms by following simple steps, ensuring they receive notifications for unauthorized login attempts. Instagram allows linking multiple devices for added convenience. Proper setup enhances account security significantly and safeguards sensitive information from potential breaches.
