How do I stop people from registering more than once?

I would like to limit registrants who complete the registration form to only be able to submit it once. How do I stop them from registering more than once?

Thanks for your help!

Hi Sharon, thank you for contacting JotForm support.

You can enable the Unique Submission option to prevent your respondents from making multiple submissions to your form. We have a detailed guide here: -to-set-unique-submissions-on-a-form

I hope this will help. Let us know if you have further questions.
