ShieldLabs detects multi-account groups from shared device, cookie and network evidence.

​
Where to integrate

Pass a stable pseudonymous User HID on authenticated activity and review the user’s event clusters. Start with the SDK for your stack and retrieve the result on your backend.

​
What to read

Read the group members, confidence and connecting evidence. Track detected, updated and resolved group changes when the separate webhook is enabled. Use the current Risk Score and flags, plus High-Risk Events where relevant. Treat a missing or incomplete result as an explicit unverified state.

​
How to act

Review repeat benefits or hold sensitive rewards for the affected accounts. Use hre.multi_account.changed for group lifecycle updates. A one-trial-per-device tutorial is a separate application policy, not an implementation of the detector.

​
Build the example

The runnable tutorial includes the starting app, the completed integration, and steps to test its behavior. Its application policy is stated separately from ShieldLabs detection. For implementation details, see Acting on results and Identification flow. Verify the expected domain, result age and account association, and consume protected actions atomically.
