to link between the facebook app and other apps with the facebook ads sdk

  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.

    So 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.

      Great explanation. Do you know of any resources where I can learn more about this? I find it really interesting.
