Duo Passport is a commercial multi-factor authentication and single sign-on tool by Duo Security. Compare features, ratings, integrations, and community reviews side by side to find the best multi-factor authentication and single sign-on fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams standardizing on vendor-agnostic authentication will find AccessMatrix UAS valuable for avoiding lock-in while supporting biometrics, FIDO2, and hardware security modules in parallel. The platform handles 100 million plus user scale and integrates with token vendors from OneSpan to Thales without custom engineering, which matters when you're already managing heterogeneous hardware across regions. Skip this if your organization needs out-of-the-box connectors to your existing identity provider; AccessMatrix is an authentication server, not a replacement for your IAM platform.
Mid-market and enterprise teams tired of authentication friction will find real value in Duo Passport's invisible authentication model, which eliminates repeated MFA prompts through continuous trust evaluation rather than point-in-time challenges. The tool's support for passwordless authentication, device memory, and cross-platform session sharing (Windows, macOS, browsers, desktop apps) means fewer login interruptions without sacrificing security posture. Skip this if your organization needs granular passwordless deployment control or deep integration with legacy on-premises identity systems; Passport prioritizes frictionless access over the configurability some enterprises demand.
