Duo Security vs WorkOS Pricing (2026)

Which one is cheaper?

One or both use custom pricing, so it depends on your specific needs.

Can I use either one for free?

Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.

How do they charge?

Different approach here. Duo Security uses per-seat pricing, while WorkOS goes with usage-based. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. Duo Security: At $3–$9/user/month, Duo sits in the affordable-to-mid range for identity security — well below Okta's MFA add-ons and competitive with Microsoft Authenticator bundles for orgs not already in the M365 ecosystem. They're clearly targeting security-conscious SMBs and mid-market teams that want enterprise-grade MFA without enterprise-grade pricing. WorkOS: WorkOS is clearly targeting mid-market SaaS companies that need enterprise auth features (SSO, SCIM, Audit Logs) without building them in-house — they're not the cheapest option, but they're cheaper than the engineering cost of rolling your own. They're competing directly with Auth0 and Okta's developer products, positioning on simplicity and transparent usage pricing rather than seat-based opacity.
