+Brokered authentication collects user credentials using the system authentication broker to authenticate an app. A system authentication broker runs on a user's machine and manages the authentication handshakes and token maintenance for all connected accounts.

 #### Use a service principal
 
 A service principal is created in a Microsoft Entra tenant to represent an app and be used to authenticate to Azure resources. You can configure your app to use service principal credentials during local development. This method is more secure than using developer credentials and is closer to how your app will authenticate in production. However, it's still less ideal than using a managed identity due to the need for secrets.

 - **System integration:** Applications that use the broker plug-and-play with the built-in account picker, allowing the user to quickly pick an existing account instead of reentering the same credentials over and over.
 - **Token Protection:** Ensures that the refresh tokens are device bound and enables apps to acquire device bound access tokens. See [Token Protection](/azure/active-directory/conditional-access/concept-token-protection).

 Windows provides an authentication broker called [Web Account Manager (WAM)](/entra/msal/dotnet/acquiring-tokens/desktop-mobile/wam). WAM enables identity providers such as Microsoft Entra ID to natively plug into the OS and provide secure login services to apps. Brokered authentication enables the app for all operations allowed by the interactive login credentials.

 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:
 
 - Azure CLI
 - Azure Developer CLI
 - Azure PowerShell
 - Visual Studio
+- Visual Studio Code
 
 The Azure Identity library can detect that the developer is signed-in from one of these tools. The library can then obtain the Microsoft Entra access token via the tool to authenticate the app to Azure as the signed-in user.

 Using dedicated application service principals allows you to adhere to the principle of least privilege when accessing Azure resources. Permissions are limited to the specific requirements of the app during development, preventing accidental access to Azure resources intended for other apps or services. This approach also helps avoid issues when the app is moved to production by ensuring it isn't over-privileged in the development environment.
