Very helpful thread!
I got the same question from a participant today. Why isn't https:// automatically used? If better protection of data is guaranteed?
If I change this in project information - distribution - URL - from http:// to https:// this will have no effect on my questionnaire that is already running?
Zitat von JensL
this is quite easy, just replace http:// for the invitation link with https:// and SSL will be activated.
