Can I create a unique login and password for each survey respondent?

You can restrict access to your survey by password. The password is saved to the Collector, so each respondent uses the same password to take the survey. To create a unique password for each respondent, you need to create a separate Collector for each respondent.

If you need to be able to match each response with the person that submitted it, you can use one of the tracking methods we have available.
