Token based authentication from xamarin

Riyasdsrc

To implement token based authentication, there are sample to use the Authentication Manger and the user credentials used to login and generate the token. Once the token generated it automatically allow the server to enabled to access and those operations handled by ArcGIS NuGet. 

            TokenCredential userCredentials = await AuthenticationManager.Current.GenerateCredentialAsync
                                        (requestInfo.ServiceUri,
                                         e.Username,
                                         e.Password,
                                         requestInfo.GenerateTokenOptions);

My question is, since the token can be created for some amount of time, is there any other way to reuse the generated token instead of creating every time with the user credentials & AUTH Manager.
