If you run out of time while filling in a questionnaire, or if you would like to be able to change your response after a bit of consideration, use the "Save & Continue" feature. This allows you to work on the questionnaire later.
Before closing the browser, think of some password, enter it in the password field, and save it.
If you want to interrupt your work on the questionnaire more than once, there is no need to enter a new password every time - one password per respondent is enough.
If you accidentally enter a password that someone else is already using for his responses, you will see an error message. In this case, please think of a different password and try again.
Only if the person who invented your password before you has been answering the same survey, the knowledge you gained by trying to use the same password enables you to view the other person's answers, though without knowing who that person is. But this is still some unavoidable privacy risk. To keep this risk as low as possible, please think of a password that is unlikely to be used by anybody else.
When you start a new browser session and go to the questionnaire again after already having worked on it, you will first see a blank questionnaire. Enter the password you used when saving your answers and click on the "Load" button. Your answers will then be loaded, and you can continue filling in the questionnaire and, if needed, edit your old answers.
Please be sure to first load your old answers before entering any new data.
