How do I prevent a respondent from responding to my survey multiple times?
Set restrictions on your survey and specify how many responses you want or when to close your survey. You can also prevent the same user from entering multiple responses.
To prevent multiple responses:
- Click Restrictions on the left pane of the Launch tab.
- Select Prevent multiple responses if you want to restrict multiple responses from a single respondent.
- One response per respondent: Restrict multiple responses from a single person.

- Respondents can update their response at any time: They can update the survey even after they've submitted it.
- One response per device: Restrict multiple responses from a single device by using browser cookies.
