Authentication & Identity
1,704 of the 1,000,000 top sites in our Tranco top-1M census run Firebase Authentication (0.2%). Google Firebase's authentication service, providing sign-in via email, phone, and third-party identity providers. Detection is homepage-level HTML/header fingerprinting, so a site can run Firebase Authentication on other pages without it showing here.
