Authentik is an open-source identity provider that handles authentication and authorization for your applications through protocols like OAuth2, OIDC, and SAML. Developers use it to centralize user management and single sign-on (SSO) across multiple apps, whether deployed on Kubernetes or standalone infrastructure. It can function as a reverse proxy, authentication server, or both, eliminating the need to build these identity features from scratch.
