A token is a personal, unique identifier given to each participant in a Survey. The system can generate random tokens when you set up participants, or you can set them manually. A token is associated with one specific person, and any personal data (first name, last name, email, and any other data you choose to specify) is linked with each token.
It is important to note that the term ‘token’ can mean two things; for us, a token is a code that uniquely identifies a Participant. By default the token code is a random string of 15 characters and numbers, but you can specify the exact tokens to be used, or the length of randomly generated tokens (in the Survey Summary Tokens panel). The token code can be used to link additional (prior) information to a specific response and/or respondent, but the token itself is meaningless -- it just a secret key that is required to gain access to a survey.
How do Tokens Work?
Enabling tokens on a survey will block access from anyone who does not have a token. We make it easy to send participants a personalized e-mail inviting them to participate, including a link to the survey with the token embedded in it.
