Multi factor authentication is an important security method that helps protect digital accounts and sensitive information from unauthorized access. Instead of relying only on a password, it requires users to verify their identity using two or more authentication factors, such as a password, mobile device, security key, or biometric scan. This additional layer of protection significantly reduces the chances of cyberattacks, including password theft and phishing. As individuals and organizations increasingly rely on digital services, understanding how multi factor authentication works and why it matters can help improve online safety and strengthen overall cybersecurity practices across various devices and platforms.
