+## Can I still perform taxonomy updates?
+
+Yes, you can still update taxonomy (termsets, terms, etc) when Azure ACS is not used. When you configure your Microsoft Entra application using the SharePoint `TermStore.ReadWrite.All` permission (delegated or application) when you want to use the CSOM taxonomy APIs. It's recommended to use the Microsoft Graph taxonomy API, for that one you need the Microsoft Graph `TermStore.ReadWrite.All` permission (delegated or application). See the [Microsoft Graph documentation](https://learn.microsoft.com/en-us/graph/api/resources/termstore-set?view=graph-rest-1.0) for more details.
