Guide to continuous authentication

This episode of Techsplainers explores continuous authentication, a security approach that keeps verifying a user’s identity throughout an active session instead of relying on a single login check. The discussion contrasts continuous authentication with traditional one-time authentication models and explains why that older “front-door only” approach leaves gaps for session hijacking, insider threats and the abuse of valid credentials. It walks through how continuous authentication works in practice, including behavioral biometrics, adaptive risk scoring and contextual signals. It also clarifies the difference between continuous authentication and adaptive authentication, showing how the two can work together as a layered trust model. Finally, the episode examines why continuous authentication is increasingly important for nonhuman identities such as service accounts, machine identities and AI agents.
