authentik
Take control of your identity needs with a secure, flexible, and open-source identity provider.
Overview
authentik is an open-source identity provider designed to give organizations complete control over their authentication and authorization needs. It serves as a robust alternative to commercial solutions like Azure/Entra ID, Ping, Keycloak, and Okta, emphasizing security through transparency and community review. By allowing self-hosting, authentik ensures that sensitive identity data remains within the organization's infrastructure, reducing reliance on third-party services. The platform is built for flexibility and scalability, offering pre-built workflows alongside extensive customization options through configurable templates, infrastructure as code, and comprehensive APIs. This allows users to tailor every step of the authentication process to their specific requirements. With support for both B2B and B2C use cases, authentik aims to provide a unified and cost-effective solution for managing identities across a wide array of applications and services, from cloud providers to internal tools.
