-## Disable key and shared access signature authentication
-
-Microsoft Entra authentication provides a superior authentication support than that's offered by access key or Shared Access Signature (SAS) token authentication. With Microsoft Entra authentication, the identity is validated against Microsoft Entra identity provider. As a developer, you won't have to handle keys in your code if you use Microsoft Entra authentication. You'll also benefit from all security features built into the Microsoft Identity platform, such as [Conditional Access](/entra/identity/conditional-access/overview) that can help you improve your application's security stance. 
-
-Once you decide to use Microsoft Entra authentication, you can disable authentication based on access keys or SAS tokens. 
-
-> [!NOTE]
-> Acess keys or SAS token authentication is a form of **local authentication**. you'll hear sometimes referring to "local auth" when discussing this category of authentication mechanisms that don't rely on Microsoft Entra ID. The API parameter used to disable local authentication is called, appropriately so, ``disableLocalAuth``.

-### Azure CLI
-The following CLI command shows the way to create a custom topic with local authentication disabled. The disable local auth feature is currently available as a preview and you need to use API version ``2021-06-01-preview``.
-
-```cli
-az resource create --subscription <subscriptionId> --resource-group <resourceGroup> --resource-type Microsoft.EventGrid/topics --api-version 2021-06-01-preview --name <topicName> --location <location> --properties "{ \"disableLocalAuth\": true}"
-```
-
-For your reference, the following are the resource type values that you can use according to the topic you're creating or updating.
-
-| Topic type        | Resource type                        |
-| ------------------| :------------------------------------|
-| Domains           | Microsoft.EventGrid/domains          |
-| Partner Namespace | Microsoft.EventGrid/partnerNamespaces|
-| Custom Topic      | Microsoft.EventGrid/topics           |
-
-### Azure PowerShell
-
-If you're using PowerShell, use the following cmdlets to create a custom topic with local authentication disabled. 
-
-```PowerShell
-
-Set-AzContext -SubscriptionId <SubscriptionId>
-
-New-AzResource -ResourceGroupName <ResourceGroupName> -ResourceType Microsoft.EventGrid/topics -ApiVersion 2021-06-01-preview -ResourceName <TopicName> -Location <Location> -Properties @{disableLocalAuth=$true}
-```
