Browser Origin Policies are used to determine which data and control flows are allowed based on the URL of the page or iFrame..

Origin Policies were initiated to prevent tracking of users from one site to another.
Origin and site are confused in many documents. An attempt at a taxonomy explaining the differences can be seen at the wiki page Cross-Origin iFrame.

Cookies stored on the user browser space are the typical means of moving data from one website to another, typically using Cross-Origin iFrames.
Note that prior to 2022 javascript could read any cookie.
