What is Risk Based Authentication?

Risk-based authentication (RBA) is an adaptive authentication method that evaluates the risk associated with a login attempt based on various factors such as location, device, time of day, and user behavior. It then adjusts the authentication requirements accordingly. For example, a low-risk login might require only a username and password, while a high-risk login could trigger multi-factor authentication (MFA) or other security challenges. RBA is commonly used to enhance security without inconveniencing users with unnecessary authentication steps for every login.
