🔐 What are tokens ?

Token are pre-generated unique values that can be used by respondents to access the survey. These tokens can be automatically generated using the token generator or you can create or import your own set of token values.

Once a token has been used by the respondent ngSurvey will link that token to the respondent responses to let you track down in the respondent reports the respondents based on the token they used.

As tokens are just text values you can easily distribute them to your respondents using any kind of electronic or non-electronic way from standard mail to phones or emails.

Each token can only be used one time by a respondent.
