Welcome back to the community, @mizanvai! Could you kindly elaborate on your issue so that the community could help you out if it’s possible with KoboToolbox?

Thank you brother @Kal_Lam Greetings!
I want to make anonymous survey, here is a problem one participant can submit only one record. I tried with online-only (one per respondent) but this one is browser based. so, there is any other way to make the survey anonymous but it will be single submission.

Hi @mizanvai, even cases like online-only and submit one record, in the incognito mode you can submit more than one. So it will not solve your problems fully i believe. If you have the pool of the beneficiaries, you can create a password like verification system so everyone can submit once with the password they have. In the simplest explanation, you will create an excel with the codes and connect it to the form, after that you will add a measure to check if this code is submitted before, and if the code existed in the data set, Kobo will not allow to submit another submissions as the password already used
