 An authenticated user ID is the opposite of an anonymous user ID. This field represents the user with a friendly name. This ID is only collected by default with the ASP.NET Framework SDK's [`AuthenticatedUserIdTelemetryInitializer`](https://github.com/microsoft/ApplicationInsights-dotnet/blob/develop/WEB/Src/Web/Web/AuthenticatedUserIdTelemetryInitializer.cs).
 
-Use the Application Insights SDK to initialize the authenticated user ID with a value identifying the user persistently across browsers and devices. In this way, all telemetry items are attributed to that unique ID. This ID enables querying for all telemetry collected for a specific user (subject to [sampling configurations](./sampling.md) and [telemetry filtering](./api-filtering-sampling.md)).

 User IDs can be cross referenced with session IDs to provide unique telemetry dimensions and establish user activity over a session duration.
