No, there are no fees at all. Authentic just means approved device state, which will be defined by the website you go to I believe. So youtube might required many different things in order to be “authentic” like no ad blockers, genuine browser, non-rooted phone, etc., whereas bank-xyz may just check for one thing, like a genuine browser. Also, websites have to enable this on their side, so its not going to be used by default on all websites. The whole thing is crap though, even if only a few websites enable this, it could have huge impacts.
