What is the result of enabling an authenticator in a survey?

Enabling an authenticator in a survey primarily serves the purpose of controlling access to the survey. This feature allows you to restrict who can enter the survey by verifying respondents' identities or ensuring that only eligible participants can contribute their responses. This is particularly important in studies that require participant confidentiality, data integrity, or adherence to specific criteria.

In control scenarios, such as research requiring specific skills or demographics, authenticators contribute to maintaining the validity of the sample. By ensuring that only authorized participants have access to the survey, the responses collected can be deemed more reliable and relevant to the research objectives.

While the other choices may seem beneficial for survey execution, they do not directly relate to the core function of an authenticator. For instance, increasing the response rate, expediting data processing, or enhancing visual design pertains to different aspects of survey management and user experience rather than the primary function of an authenticator.
