Risk-Based Authentication
Oct 18, 2023
Risk-based authentication is a layer of security designed to assess the probability of account compromise with each login. If a system detects an unusual request or suspects malicious activity, it usually asks users to verify their identity through various methods. Examples of risk-based authentication include:
- Being prompted by a system to authenticate yourself via biometric authentication.
- A website asks users to enter a code sent to a mobile device.
- An application requiring two-factor authentication when attempting to log in from an unknown location.
- Answering security questions to access sensitive data.
