You can set the cookie to secure by updating the uTag loader file. This file is the backbone of Tealium on your site, so please be cautious in editing it. You can access this by clicking on your name in the upper right hand corner and clicking on manage templates from the drop down menu. From there you can select the uTag loader template and edit the following line (line 423) from:
document.cookie = a + “=” + v + “;path=/;domain=” + utag.cfg.domain + “;expires=” + x;
document.cookie = a + “=” + v + “;path=/;domain=” + utag.cfg.domain + “;expires=” + x + “;secure”;
General question: Would it have a drawback to set all cookies to secure? This could be an option in the iQ settings or a general feature.
I was requesting this feature already and I don't think that it would be a big thing to do. Plus it would help a lot of data security staff in the EU to comply to GDPR regulations.
