Take Control of Identity with authentik

Managing identity and access is one of the most critical parts of modern infrastructure. Whether you’re building for internal teams, customer platforms, or B2B environments, how you secure and manage access matters. That’s where authentik comes in.

authentik is an open-source Identity Provider (IdP) designed to be both flexible and powerful. With support for modern protocols like OAuth2, OpenID Connect, SAML2, LDAP, and RADIUS, it delivers everything you'd expect from a cloud IdP, without surrendering control of your data or depending on a third-party platform.

Why authentik?

At its core, authentik is about regaining control. By self-hosting your IdP, you eliminate the risks associated with SaaS identity platforms. You own the infrastructure, the policies, and the data. For companies looking to replace tools like Okta, Auth0, Entra ID, or Ping Identity, authentik is a full-featured, scalable alternative that can meet enterprise demands.

Security is a first-class citizen in authentik’s design. Because it's open-source, its code is continuously reviewed by a global community of experts. There’s no black box, just transparent, auditable software built with modern security principles.

Built for Scale and Flexibility

authentik adapts to your environment. Use it out of the box or shape it to match the most complex requirements. You can configure every part of the login experience through policies, templates, and APIs. Whether you deploy with Docker, Kubernetes, or Terraform, authentik fits naturally into your existing workflows.

With prebuilt components and infrastructure-as-code support, you can automate deployments and roll out changes consistently across environments. Want to streamline your DevOps? authentik has you covered.

Simplify Identity at Every Level

Organizations use authentik to address a broad set of identity challenges:

• Internal Access: Deliver Single Sign-On (SSO) for internal tools and services, giving employees one password for everything.
• Customer Identity Management: Customize user authentication and account flows for SaaS apps and portals.
• Legacy Integration: Modernize older apps without built-in authentication through proxy-based access.
• Zero Trust Security: Enforce granular, adaptive access controls based on identity, device posture, and location.
• Secure Remote Access: Access internal servers like RDP, SSH, and VNC securely, without the need for VPN.
• Multi-factor Authentication: Centralize MFA enforcement with support for TOTP, WebAuthn, and passkeys.

You can even delegate control. Give users the ability to manage their own profiles and passwords, reducing support overhead and improving user satisfaction.

Enterprise-Grade Security

authentik brings advanced security features typically found in commercial identity platforms:

• GeoIP and Impossible Travel Detection to identify suspicious logins.
• Session Binding to tie sessions to specific networks or geolocations.
• FIPS Compliance to meet strict federal security requirements.
• Comprehensive Audit Logging for compliance and forensics.
• Passwordless Authentication with full support for WebAuthn and passkeys.

All of this is delivered through an architecture that supports Zero Trust out of the box.

Built for Seamless Integration

You don’t need to overhaul your tech stack to adopt authentik. It integrates with your existing systems using standard protocols:

• OAuth2 and OpenID Connect for modern applications
• SAML2 for enterprise environments
• LDAP and RADIUS for legacy systems
• SCIM for automated provisioning
• Application proxy support for apps without native authentication

Whatever you're using, authentik is designed to slot in smoothly, without compromise.
