Microsoft supports three ways to join a Windows device to an identity infrastructure. Understanding your join type is the first step in selecting the right TruU authentication modality.
For a quick summary of which TruU modality applies to each join type, see TruU Windows Authenticator Modalities.
For Microsoft’s full documentation on device identity, see What is a device identity? on Microsoft Learn.

The following table describes all three join types — what each means, how devices authenticate, how they are managed, and their access to on-premises and cloud resources.
To check your device’s join type, run dsregcmd /status in PowerShell and inspect the AzureAdJoined and DomainJoined fields.
