In practice that number could be much higher; the documentation suggests a 16-bit cohort ID comprising 4 hexadecimal characters.&lt;p&gt;Also, its since someone can belong to more than 1 cohort, the 8bits is a bare minimum and not a maximum. For instance, techie who likes hiphop, buys whisky and is looking for a washing machine is 32bits of entropy and covers the billion users with ease.</text><parent_chain><item><author>eterevsky</author><text>While I do understand that some people may not like it, I don&amp;#x27;t see how FLoC is particularly harmful.

They are talking about narrowing down to thousands of users, while in fact if Chrome has on the order of a billion users, and if FLoC has only 8 bits of entropy, the actual number of users in a cohort is on the order of millions. Secondly, from my understanding this cohort is based on your recent activity, so it will change over time.</text></item></parent_chain></comment><story><title>How to fight back against Google FLoC</title><url>https://plausible.io/blog/google-floc</url></story>
