Re: [proposals] Interoperable Private Attribution (IPA) (#2)

> The proposal also seems to assume that the user is logged in to at least one match key provider. What happens if the user is not? Does the browser make up a device identifier?

This is still yet to be determined. One idea is that the device could generate a random match key, which would at least default to "same device attribution".

This would entirely depend which match key providers the source sites and trigger sites are using. If those sites are using match key providers that the user is not logged into, then they attribution would likely be missed. 100% coverage have never been possible, but this API is designed to create as much coverage as possible, without enabling user level tracking.
