 For this example, we create a [``ClientSecretCredential``](/javascript/api/@azure/identity/tokencredential) instance by using client and tenant identifiers, along with a client secret.

 You can obtain the client ID, tenant ID, and client secret when you register an application in Azure Active Directory (AD). For more information about registering Azure AD applications, see [Register an application with the Microsoft identity platform](../../active-directory/develop/quickstart-register-app.md).
