From LimeSurvey Manual
If your survey uses tokens and your responses are not anonymized, you may want to enable this feature. If you turn this on, your participants will be able to leave the survey and resume later at any time without using the "Resume later" function - for example, when they get distracted or their browser crashes. Upon clicking the invitation link again, they will find their survey answers still in place when they return to the survey and will even find themselves on the same page where they were before leaving.
