You can import devices connected to Azure Active Directory (AD) into the administration panel and use them to set limitations when adding security key policies.
Azure AD Connected PCs
Reach out to this section to import already-joined PCs from Azure AD to use in Security Key Policies to limit access to specific devices. To join and list Azure AD connected PCs, the only required step is providing enough permission.
Click on Import Azure AD-Connected Devices and choose the account that you want to connect to.
Then you will be redirected to your IDmelon panel, and you can see the added devices.
Note: that you may need to sign-in again during the redirection.
