AuthZed vs. Authorizer Comparison Chart

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™. Auth0 lets you quickly 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 a customized, secure, and standards-based single login. Universal Login connects users to a central authorization server. Credentials aren’t transferred across sources, which boosts security and protects against phishing and credential stuffing attacks. OAuth 2.0 recommends that only external user agents (like the browser) be used by native applications for authentication flows. Auth0’s Universal Login achieves this while enabling SSO.

Authentication happens at some of the most important, and highly impactful, places in your customers' journey. Take control of user authorization with a passwordless authentication, social integrations, and enterprise SSO. Support the branding of all your customers with custom domains and a fully customisable UI by bringing your own pages and designs. Integrate with complex requirements and run your own code during authentication using our powerful workflows. Organise all your business customers using organizations to easily segergate them and fine tune the authentication experience to their individual needs.
