A new Cybersecurity Practice Guide demonstrates how online retailers can implement open, standards-based technologies to enable Universal Second Factor (U2F) authentication by consumers at the time of purchase when risk thresholds are exceeded
Multifactor Authentication for E-Commerce
- Retailers can implement multifactor authentication (MFA) to reduce the opportunity for a customer’s online account to be used for fraudulent purchases.
- MFA is a security enhancement that allows a user to present several pieces of evidence when logging into an account. This evidence falls into three categories: something you know (e.g., password), something you have (e.g., smart card), and something you are (e.g., fingerprint). The presented evidence must come from at least two different categories to enhance security.
- The National Cybersecurity Center of Excellence (NCCoE) at the National Institute of Standards and Technology (NIST) built a laboratory environment to explore MFA options available to retailers today, and documented the example implementations that retailers can consider for their environment.
- This NIST Cybersecurity Practice Guide demonstrates how online retailers can implement MFA to help reduce electronic commerce (e-commerce) fraud.
