# AuthenticationResultType


The object that your application receives after authentication. Contains tokens and information for device authentication.

This data type is a response parameter of authentication operations like [InitiateAuth](API_InitiateAuth.md), [AdminInitiateAuth](API_AdminInitiateAuth.md), [RespondToAuthChallenge](API_RespondToAuthChallenge.md), [AdminRespondToAuthChallenge](API_AdminRespondToAuthChallenge.md), and [GetTokensFromRefreshToken](API_GetTokensFromRefreshToken.md). `GetTokensFromRefreshToken` doesn't return `NewDeviceMetadata`.
