+[Create an Azure Cache for Redis instance using the official Microsoft documentation.](https://docs.microsoft.com/azure/azure-cache-for-redis/quickstart-create-redis)
+
+In your Redis component, you can implement EntraID support for Azure Cache for Redis with the following metadata settings:
+
+```yml
+metadata:
+  - name: redisHost
+    value: MYHOSTNAME.redis.cache.windows.net:6380
+  - name: useEntraID
+    value: "true"
+  - name: enableTLS
+    value: "true"
+```
+
+In order to use EntraID:
+
+- The `redisHost` name must be specified in the form of `"server:port"`
+- TLS must be enabled
+
+`useEntraID` assumes that either your UserPrincipal (via AzureCLICredential) or the SystemAssigned managed identity have the RedisDataOwner role permission. If a user-assigned identity is used, [you need to specify the `azureClientID` property]({{< ref "howto-mi.md#set-up-identities-in-your-component" >}}).
