Auth0 Platform vs Duo Passport: Side-by-Side Comparison (2026)

Auth0 Platform

Developer teams building customer-facing applications need Auth0 Platform because it eliminates the authentication infrastructure tax, letting engineers ship passwordless login and adaptive MFA without building IAM from scratch. The platform covers NIST CSF 2.0 PR.AA identity and access control requirements across cloud deployments at scale, and its Organizations feature handles B2B multi-tenancy patterns that otherwise require months of custom work. Skip this if your priority is on-premises federation or you need deep authorization policy engines; Auth0's fine-grained authorization APIs are solid but secondary to its authentication strength.

Duo Passport

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.
