Hello!
I am very curious about the generation logic of ECID. According to the official document: In the context of Identity Service, ECID is used as the primary ID for devices and as a base node for identity graphs. I found that there are multiple ecid for the same cookie, so what factors are involved in judging the uniqueness of the ecid? If possible, please provide examples.
Thanks,
Gwen
Ok, I think I am going to need some more information... what is cookie (id:451-VAW-614&token:_mch-ssga.com-1586790412737-50592)?
Is that a cookie that your system is setting?
Depending on your implementation, users could get an initial ECID on your website, and a second one on your apps... if you install the extension to pass the App's ECID to the website (when opening the website from the app), or appending the ECID from one site to another site in a multi-site organization... a user can be moved from one ECID to another in an effort to stitch them together. While Adobe does it's best to properly identify users and set the same ECID to a user, the way in which people use and interact with sites and browsers, and as more and more privacy concerns are raised around cookie usage, passing ECIDs between different instances are used to help improve tracking, but this can result in users having their ECIDs updated/changed... which might be what you are seeing.
Here are some resources I found around ECID:
