Authentik is an open-source identity provider (IdP) designed for authentication, Single Sign-On (SSO), and access management. It allows organizations to manage user identities and secure application access through modern authentication standards.

The platform supports protocols such as SAML2, OAuth2, LDAP, and RADIUS, and includes features like multi-factor authentication, application proxy, and infrastructure-as-code configuration. Authentik is self-hostable and commonly used as an alternative to identity solutions such as Okta or Azure AD.
