Authentication & Identity
324 of the 1,000,000 top sites in our Tranco top-1M census run Auth0 (0%). An identity and authentication platform (Okta) offering login, SSO, and user-management APIs. Detection is homepage-level HTML/header fingerprinting, so a site can run Auth0 on other pages without it showing here.
