What does AEP uses to recognize anonymous visitors?

[Michael_Soprano]

I noticed that if I delete all of my cookies from the browser AEP still recognizes me as the same user. 

Do you know what AEP uses except for cookies to track users? Is it IP address?

Do you know where can I find info about this?

Hello @Michael_Soprano  the ECID is stored in the local storage and in cookies. If you change your browser or clear all application data then it won't be able to recognize you.

Hi @Michael_Soprano 

If you're not setting s.visitorID and using identity service for visitors identification then Adobe uses ECID followed by a fallback ID if ECID is not available if none of this is available then IP is used to identify visitors.

Check this document for more details.

Can we extend this by using Fingerprint.JS or any other 3rd party cookies (like FB or Google's)?

Thanks

yes, In AEP you can define multiple identities in your schema followed by a single primary identity of standard and custom identity namespaces, Identity service then will merge all these fragments to provide you a holistic user profile.
