Peri Doerfler of the NYU Tandon School of Engineering discusses a recently published paper and research conducted by NYU and Google looking into the efficacy of login challenges in deterring account takeover attacks. The research examined a sample of 1.2 million users and 350,000 hijacking attacks and the success of things like knowledge-based challenges, on-device prompts, SMS two-factor authentication and more in holding off account takeover attacks.
