Authentication & Identity
5,195 of the 1,000,000 top sites in our Tranco top-1M census run Google Identity Services (0.5%). Google's library for adding sign-in and account authentication, including Google One Tap and OAuth, to a site. Detection is homepage-level HTML/header fingerprinting, so a site can run Google Identity Services on other pages without it showing here.
