You can't authenticate asynchronously -- the original request is stalled untill the out-of-process call returns, and there is no way to release the thread / connection pool it is using. For the original poster's question: a ScriptableMultiplugin can contain PythonScripts, ExternalMethods, etc., as well as a RAMCacheManager. You could implement 'authenticateCredentials' to call an ExternalMethod, for instance, and then cache the result. You still need to find a way to deal with the edge case where the service is unavailable: for instance, you might need to use a module which allowed for timeouts on the service call.
