->MSAL Python's [built-in Managed Identity (MI) sample](https://github.com/AzureAD/microsoft-authentication-library-for-python/blob/1.29.0/sample/managed_identity_sample.py#L38-L42) showcases how user-assigned managed identity can be inferred from environment variables. It's an advanced usage pattern that can be used instead of explicit definition of the client ID in code.

 By default, MSAL Python supports in-memory caching.

->MSAL Python also supports cache extensibility for managed identity, so that you may persist the token cache on disk. This can be useful if you are writing a command-line script and a few other limited scenarios. We **do not recommend** sharing managed identity token cache among multiple machines as this can result in unexpected access behaviors for users of the cache.
