Dynamic risk-based authentication (RBA) is an advanced security method that adapts authentication requirements in real-time based on the risk associated with each login attempt, offering a solution to the limitations of static methods like passwords. By evaluating various contextual factors such as geolocation, device information, and behavioral biometrics, RBA minimizes false positives and enhances user experience by requiring additional authentication only when necessary. The risk engine at the core of RBA combines rule-based systems and machine learning algorithms to assign risk scores, which determine the level of authentication needed for each attempt. Liveness detection, crucial in this system, ensures the user is physically present, countering threats like deepfakes. Implementing RBA enhances security, improves user experience, reduces false positives, and aids compliance with regulatory requirements. Didit provides a platform that supports RBA through modular architecture, workflow orchestration, machine learning-powered risk engines, and seamless integration options.
