 ## Assign Azure roles for access to data
 
 When an Azure AD security principal attempts to access blob data, that security principal must have permissions to the resource. Whether the security principal is a managed identity in Azure or an Azure AD user account running code in the development environment, the security principal must be assigned an Azure role that grants access to blob data. For information about assigning permissions via Azure RBAC, see [Assign an Azure role for access to blob data](assign-azure-role-data-access.md).

 ## Get an authenticated token credential
 
 To get a token credential that your code can use to authorize requests to Blob Storage, create an instance of the [DefaultAzureCredential](/dotnet/api/azure.identity.defaultazurecredential) class. For more information about using the DefaultAzureCredential class to authorize a managed identity to access Blob Storage, see [Azure Identity client library for .NET](/dotnet/api/overview/azure/identity-readme).
