Reverse Autheneticator - prevent multiple responses from the same participant using their mail in anonymous surbey. | XM Community
Skip to main content

I have a survey built which will be going out via anonymous link. We will not be collecting any identifiable data. Because the survey will be distributed by many participating organizations - we know that there will likely be overlap in respondents. To prevent duplicate responses - we are working on setting up an email authenticator which (when programmed correctly) will ask for an email - add that email to a directory through workflow at the completion of the survey and then use that directory as a source for the authenticator - not allowing someone who has been added to the directory (by completing the survey) to start the survey again.

However - the survey currently is not allowing anyone to move past the email input - immediately displaying a ‘Unable to log in with the information provided.’ error message (even in incognito mode). I checked the directory and it is not adding emails there either. 

Please help!

So update on this: 

The authenticator portion now works. In that someone can enter their email and move past the authenticator because they ‘fail’ (their email is not in the directory). However - the form field question is not populating the directory and so when I complete the survey and try to retake - it is letting me because I once again ‘fail’ authentication. Anyone? Customer Chat support is not helping.

Hi ​@kepkam,

Has the issue been fixed? If not, I can escalate the issue internally.

​@kepkam,

What does your workflow look like? What does the run history say?

 

​@TomG and ​@AlonsoC  - no it has not been fixed.

The problem - (according to support) is that when there are dups in the directory - the authenticator will not work. However - question #1 - asking for the email to add to directory is creating a dup when I re-enter the survey.

The settings for the workflow have - ‘update existing’ checked. So not sure what is going on there.

​@kepkam ,

I believe your directory isn’t set up to use email as the unique key. Depending on your account, you may be able to create a new directory that uses email as the unique key then create your contact list in that directory. Another option would be to update the directory to use email as the unique key, but that is risky because it may have unintended consequences.

 

I also struggle with duplicates in open surveys, so I'll give this approach a try as well
