authentik is an open-source Identity Provider (IdP) for modern SSO. It supports SAML, OAuth2/OIDC, LDAP, RADIUS, and more, designed for self-hosting from small labs to large production clusters.
Our enterprise offering is available for organizations to securely replace existing IdPs such as Okta, Auth0, Entra ID, and Ping Identity for robust, large-scale identity management.
