+#### App Secret
+
+An App Secret (also called a client secret) is a string used for securing communication between an application and Azure Active Directory (Azure AD). It is a credential that the application uses along with its client ID to authenticate itself when accessing Azure resources, such as APIs or other services, on behalf of a user or a system.
