 # Authenticate .NET apps to Azure services during local development using developer accounts
 
-During local development, applications need to authenticate to Azure to access various Azure services. You can authenticate locally using a developer account, a [broker](local-development-broker.md), or a [service principal](local-development-service-principal.md). This article explains how to use a developer account. In the sections ahead, you learn:
+During local development, applications need to authenticate to Azure to access various Azure services. You can authenticate locally using one of these approaches:
 
-- How to use Microsoft Entra groups to efficiently manage permissions for multiple developer accounts
-- How to assign roles to developer accounts to scope permissions
-- How to sign-in to supported local development tools
-- How to authenticate using a developer account from your app code

 For an app to authenticate to Azure during local development using the developer's Azure credentials, the developer must be signed-in to Azure from one of the following developer tools:

-Developers can use [Azure Developer CLI](/azure/developer/azure-developer-cli/overview) to authenticate. Apps using <xref:Azure.Identity.DefaultAzureCredential> or <xref:Azure.Identity.AzureDeveloperCliCredential> can then use this account to authenticate app requests when running locally.

 To authenticate with the Azure Developer CLI, run the `azd auth login` command. On a system with a default web browser, the Azure Developer CLI launches the browser to authenticate the user.
 
 ```azdeveloper
 azd auth login
 ```
 
-For systems without a default web browser, the `azd auth login --use-device-code` uses the device code authentication flow. The user can also force the the Azure Developer CLI to use the device code flow rather than launching a browser by specifying the `--use-device-code` argument.

 To authenticate with Azure PowerShell, run the command `Connect-AzAccount`. On a system with a default web browser and version 5.0.0 or later of Azure PowerShell, it launches the browser to authenticate the user.
