Secure authentication without per-user pricing. Open source Auth0 alternatives for SSO, MFA, passwordless login, and user management you own.
Auth0 simplifies the process of adding secure login and user management to applications. It handles crucial tasks like registration, password resets, multi-factor authentication, and user profile management, allowing developers to focus on building their core product. While powerful, Auth0’s commercial nature and vendor lock-in can be drawbacks for some projects. Users often seek open source alternatives to maintain greater control over their data, avoid recurring costs, and customize the platform more extensively.
The core value proposition of Auth0 lies in its comprehensive suite of features. Universal Login, Single Sign-On (SSO), and robust security protocols like Multi-Factor Authentication are key draws. However, the need for customization and self-hosting can drive developers to explore alternatives that offer more flexibility. Furthermore, concerns regarding data privacy and compliance may lead users to prefer the transparency of open source solutions.
Use cases for Auth0 are diverse, spanning from securing web and mobile applications to enabling authentication in APIs and microservices. Increasingly, Auth0 is being used to secure AI agents, which necessitates strong identity and access controls. However, for projects with specific security requirements or limited budgets, finding a self-managed open source Auth0 alternative is often desired.
