Multi-Factor Authentication
Multi-Factor Authentication (MFA) is a security mechanism that requires users to provide two or more verification factors to access a system, application, or resource. It enhances security by combining something the user knows (like a password), something the user has (like a smartphone or token), and/or something the user is (like a fingerprint). This approach significantly reduces the risk of unauthorized access due to compromised credentials.
Developers should implement MFA in applications handling sensitive data, such as financial systems, healthcare platforms, or enterprise software, to protect against phishing, credential theft, and brute-force attacks. It is essential for compliance with regulations like GDPR, HIPAA, or PCI-DSS, and is increasingly a standard security practice for user-facing applications to safeguard accounts.
