Improved New Device Behavior Detection
Improved New Device Behavior Detection supports browsers that store HTTP cookies. Device behavior detection is based on data passed from a web browser and a trusted application. See Security Behavior Detection for more information about securing your org based on end-user activity and behavior.
Web browsers limitations
- If Improved New Device Behavior Detection is enabled for your org, sign-in activity from a device using a browser without an HTTP cookie is treated as a new device with limited accuracy.
Trusted applications are responsible for identifying devices as part of new device detection.
- If Improved New Device Behavior Detection is enabled for your org, you can send a unique identifier for each device using
deviceTokenin the context object. See Authentication context object.
- Sign-in activity from a device is identified as a new device when the unique identifier is not sent by a trusted application.
If Improved New Device Behavior Detection is not enabled for your org, you can send a unique identifier for each device using the
X-DEVICE-FINGERPRINTheader. See Primary authentication with device fingerprinting.
To learn how to generate a unique identifier, see Device fingerprint best practices.
Note about device detection
- Browser support for browser fingerprinting only provides best effort accuracy due to web browser vendors such as Apple and Mozilla reducing fingerprint accuracy in their browsers.
The browser fingerprint may change over time as the same browser fingerprint may be sent from multiple devices.
As a result, Okta recommends enabling Improved New Device Behavior Detection for more accurate detection.
