 # Get access keys for Event Grid resources (topics or domains)
-Access keys are used to authenticate an application publishing events to Azure Event Grid resources (topics and domains). We recommend regenerating your keys regularly and storing them securely. You are provided with two access keys so that you can maintain connections using one key while regenerating the other.

 This article describes how to get access keys for an Event Grid resource (topic or domain) using Azure portal, PowerShell, or CLI. 
 
+> [!IMPORTANT]
+> From August 1, 2024 to August 10, 2024, Azure Event Grid will rollout a security improvement extending the Shared Access Signature (SAS) key length from 44 to 84 characters. This change is being made to strengthen the security of your data in Event Grid resources. The change doesn't impact any application or service that currently publishes events to Event Grid with the old SAS key but it may impact only if you regenerate the SAS key of your Event Grid topics, domains, namespaces, and partner topics, after the update. 
+> 
+> We recommend that you regenerate your SAS key on or after August 11, 2024. After regenerating the key, update any event publishing applications or services that use the old key to use the enhanced SAS key.

 ## Azure portal
