Hello,


I want to secure my survey with a password to avoid that others will complete it.


As part of a larger project, there's an intranet portal that contains a link to the survey. All members of the project have a login to that intranet and can see the survey link there. I want to mention the login/pass for the survey there as well. As such, only members can complete the survey
Since I do not know the members in advance, I cannot use a token based system to give individual access to the survey, hence my question whether it's possible to protect the survey with a single password that's only known to a group of people that can complete the survey in an individual way.

Many thanks in advance for answering this question,
Kind regards,
Patrick

Yes, please refer to the manual.

You could prefill a hidden question via the survey URL and then either...

1) Use relevance based on that question to hide groups/questions and display a "This is a private survey" message.

2) Use Expression Manager to load a question that triggers a quota.

Or, why not install LimeSurvey on a server accessible only via the intranet?
