Auth0 takes a modern approach to Identity, providing secure access to any application, for any user. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™.

Authenticate users across all applications with a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server.
