Which of the following is NOT a purpose of Survey Authentication?

Survey Authentication primarily serves significant purposes such as ensuring data integrity, verifying respondent identity, and maintaining data credibility. The aim is to confirm that the data collected is accurate and trustworthy by preventing unauthorized access and ensuring that responses come from verified individuals.

The assertion that reducing survey length is a purpose of Survey Authentication is not accurate. In fact, authentication processes may add steps to the survey experience, which could potentially increase the length of time a respondent takes to complete the survey. Therefore, reducing survey length does not align with the primary functions of Survey Authentication, making it the correct choice for this question.
