#Authentication By default, AutoRest generates clients that make unauthenticated HTTP requests. When the -AddCredentials flag is set to true, the generated client will include a Credentials property of type ServiceClientCredentials. The Microsoft.Rest.ClientRuntime package includes two ServiceClientCredentials :

• TokenCredentials - used for OAuth authentication.
• BasicAuthenticationCredentials - used for basic username/password authentication.

Custom authentication behaviors can be implemented by inheriting from ServiceClientCredentials. The ProcessHttpRequestAsync() method is invoked for each HTTP request.
