It is possible to require a Swarthmore login to take a Qualtrics survey.  This is helpful when publishing a survey URL on a public web page in order to limit respondents to the Swarthmore community.  Qualtrics can automatically capture name, username, email, and other user information from the login process and this data can be used within the survey or saved in the response.  

Contact ITS for assistance in setting up password protected surveys.
