They can’t use your Facebook account or something else for that? I’m pretty ignorant about ad tech, it’s something I’d like to learn more about.

- babypuncher 5y agoSo here's how IDFA works. User logs in to the Facebook app, and Facebook ties the user's IDFA to their Facebook account. User opens non-Facebook app X that uses the Facebook SDK for ads/tracking. App X sends the IDFA to Facebook, who then looks it up in their database and sees it on your account. They can now tie all user activity tracked by app X to the user's Facebook account. Without IDFA, this kind of cross-app tracking becomes considerably more difficult.
- FearlessNebula 5y agoGreat explanation. Do you know of any resources where I can learn more about this? I find it really interesting.
