Designed with developers in mind, FusionAuth integrates seamlessly with any language, framework, or architecture. Every capability is API-first and built for extensibility, so you can tailor authentication workflows without getting locked into rigid, inflexible systems.

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. 4.4 out of 5 stars 1,122 Ratings Visit Website for Auth0 Keeper Security Keeper Security is transforming the way people and organizations around the world secure their passwords and passkeys, secrets and confidential information.

AuthStack: About AuthStack is a host anywhere, Enterprise-grade, Single Sign-On (SSO) and Identity Access Management (IAM) System. It assumes responsibility for logging in users to your own, and optionally third-party websites and applications. Rather than managing multiple different logins for each website and application, AuthStack centralizes your user identity management so the user only has to login once and maintain one password and profile. Integration with AuthStack requires no custom coding if your website or application already supports SAML. If SAML is not supported we provide a Connector Framework, free of charge. We can also help you integrate the Connector if required. There is also no need to migrate your existing user database(s). AuthStack bundles with a Connector Framework which can communicate with any data source, whether that's LDAP, MySQL, SOAP, REST API, etc, to check credentials from existing user databases.	ZITADEL: About ZITADEL is an open-source identity and access management platform designed to simplify authentication and authorization for applications. It offers a comprehensive suite of features, including customizable hosted login pages, support for modern authentication methods such as Single Sign-On (SSO) and social logins, and enforcement of multifactor authentication to enhance security.

The platform supports role-based access control, allowing for precise permission assignments based on user roles, and is inherently multi-tenant, facilitating easy extension of applications to new organizations. ZITADEL's extensibility enables seamless adaptation to various workflows, user management processes, and brand guidelines, with features like ZITADEL Actions that execute workflows after predefined events without the need for additional code deployment.
