authentik vs OneLogin Modern Multi-Factor Authentication: 2026 Comparison

authentik

Startups and SMBs that need SSO and MFA without vendor lock-in should run authentik; the open-source model means you own the codebase, avoid licensing creep as you scale, and can self-host or go hybrid without renegotiating contracts. It covers NIST PR.AA identity management and access control natively, and the built-in application proxy handles remote access to RDP, SSH, and VNC without bolting on a separate tool. Expect to staff more ops lift than a SaaS alternative; this is not the tool for teams wanting a hands-off managed identity service.

OneLogin Modern Multi-Factor Authentication

Mid-market and enterprise teams replacing aging SMS-based MFA will see immediate risk reduction from OneLogin Modern Multi-Factor Authentication's adaptive authentication engine, which evaluates login context and device posture before enforcing MFA policy. SmartFactor Authentication uses machine learning to flag anomalous access patterns, reducing friction for legitimate users while catching the majority of credential-stuffing attacks without additional overhead. Skip this if your organization requires hardware security key enforcement as the primary method or needs deep integration with legacy on-premises identity systems; OneLogin's strength is cloud-native deployments where passwordless and risk-based policies can actually take effect.
