Passive authentication is a method of verifying user identities unobtrusively by analyzing how a user naturally uses their device or app, the device's characteristics, or the user's biometrics, without requiring active input from the user. It provides frictionless, continuous identity validation throughout user interactions. It can include biometric authentication, multi-factor authentication (MFA), and passive liveness detection for added security.
Use case/ examples for passive authentication
Continuous verification:
Analyzing user behavior patterns, such as typing rhythm and the user's interaction with their device, to authenticate identity passively and unobtrusively on a continuous basis throughout the user's login session.
Anomaly detection: Flagging accounts when device usage patterns deviate significantly from established baselines, indicating potential takeover.
High-risk transaction approval: Triggering the use of additional authentication, like biometrics or OTP, for large fund transfers, account recovery, password resets, or new devices.
