Single response per user.

Hi @pipapublicidade,

You can set the number of limits in the quiz and poll the users try to attempt.

To make the poll answered only once, please refer to our documentation here: https://quizandsurveymaster.com/docs/creating-quizzes-and-surveys/basic-settings/#limit-attempts

QSM allows you to limit the attempts that you can set to 1.
If you still find the confusion, let me know, and I’ll be happy to assist.

Regards,
Sumit
