Why should you disable "Save and Continue" when using an authenticator?

Disabling "Save and Continue" when using an authenticator is important primarily because it prevents respondents from being able to complete multiple responses. Authenticators ensure that each respondent is uniquely identified, meaning that if the "Save and Continue" option is enabled, it could allow individuals to return and submit multiple responses to the survey, effectively skewing the data and impacting the integrity of the results. This is critical in studies where each participant should only provide one response, ensuring that the insights derived from the data are accurate and reliable.

In contrast, keeping the "Save and Continue" option might be beneficial in other contexts, but when an authenticator is in place, it can lead to complications with data validity and uniqueness of responses.
