01 - Login
In order to use the Write-Back the user must always be authenticated. This can either happen automatically or you will need to introduce the username and password, typically will be the same that you use to login on the Tableau Server. However if you are not sure please check with the technical responsible for Write-Back, we do support multiple authentication mechanisms and it is up to your organization to decide the more suitable option.
If you are using the Write-Back on Tableau Server and you didn't have to login in there, it means you probably won't need to and the login was done automatically.
When using a basic configuration for doing a trial the default user names/passwords are: user1/password ; user2/password; user3/password.
