Difference between registering an application in the app registrations pane and adding an application in the enterprise applications pane in Microsoft Entra admin center or Azure portal. App registration is a way of reserving an app and URL with Azure Active Directory (Azure AD/Microsoft Entra), allowing it to communicate with Azure AD, hooking up any reply URLs, and enabling Azure AD services on it. When we have an application that we're developing and want to integrate it with Azure, we need to register our application in app registrations, where we'll configure the reply URL, logout URL, and API access, if needed. When we register our application, Azure AD assigns a unique application ID to it and lets us add certain capabilities, such as credentials, permissions, and sign-ins. The default settings allow only users from the tenant under which our app is registered to sign in to your application. App Registrations Pane New App registration screen It's possible to confuse
