Auth0 Signals is brought to you by Auth0

Auth0 is composed of multiple components, one of them is the Anomaly Detection engine that constantly evaluates multiple signals.

  1. Malicious login traffic is detected with Auth0’s Anomaly Detection engine. This helps protect our customers from automated attacks, such as credential stuffing.
  2. The engine consumes multiple risk signals, such as domain reputation and breached password detection to understand a source’s risk level.
  3. We refer to this data as Auth0 Signals and make many freely available to everyone via API to help you combat automated attacks with adaptive authentication.
  4. Learn more about Anomaly Detection with Breached Password Detection.
