    Auth0 by Okta takes a modern approach to Identity and enables organizations to provide secure access to any application, for any user. Auth0 is highly customizable, and simple yet flexible. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is a part of Okta, The World’s Identity Company™. With Auth0, you can rapidly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control. Authenticate users across all applications with your own custom, secure, and standards-based unified login. With Universal Login, users are redirected to a central authorization server. Because authentication takes place on the same domain as the login, credentials are not sent across sources, increasing security and protecting against attacks like phishing and credential stuffing. OAuth 2.0 recommends that only external user agents (like the browser) should be used by native applications for authentication flows. Universal Login provides this in a secure manner while also enabling SSO.
