From LimeSurvey Manual
Yes, tokens can be used both for anonymous and non-anonymous surveys. This is determined when creating a survey. If a survey is not anonymous (or 'tracked') then the token list can be used to find the responses that an individual has made to the survey. If the survey is anonymous, then no link (technically: foreign key relationship) is available between the respondents from the survey participants table and their corresponding answers.
