**Note:** When Azure Identity library credentials are used with Azure service libraries (for example, Azure Blob Storage), the in-memory token caching is active in the `HttpPipeline` layer as well. All `TokenCredential` implementations are supported there, including custom implementations external to the Azure Identity library.

#### Disable caching

As there are many levels of cache, it's not possible to disable in-memory caching. However, the in-memory cache may be cleared by creating a new credential instance.
