Hello! Yes, you're on the right track—when the Intune app asks for an Azure Client ID and Azure Secret Name, it typically means the application is trying to authenticate via Microsoft Entra ID (formerly Azure AD) using an app registration. Creating a registered app in Entra ID is indeed the correct first step. After registering the app, you should use the Application (client) ID as the Client ID. For the secret, you must generate a new Client Secret under the "Certificates & secrets" section of your registered app—not the Secret ID, but the actual value of the secret, which is only visible right after you create it. This value is what you should enter as the Azure Secret Name. Also, ensure that the registered app has the appropriate API permissions for Intune  and that admin consent has been granted. Double-check these details, and you should be able to authenticate successfully. 

Thank you. After double checking everything, I was using the incorrect name for .onmicrosoft.
