WorkOS vs Auth0: Which Auth Platform Should You Use in 2026?

A factual comparison of WorkOS and Auth0 covering pricing, SSO/SCIM costs, free tier limits, and which is the better fit for B2B SaaS vs consumer apps.

Updated 2026-09 · 2026

WorkOS

Enterprise-ready auth APIs built for B2B SaaS

FreeUser Management free up to 1M MAUs; SSO/SCIM from $125/connection/mo

Strengths

+User Management is free for up to 1,000,000 MAUs
+Pay-per-connection pricing scales cleanly as you sign up enterprise customers
+Built-in self-serve Admin Portal for customers to configure their own SSO/SCIM

Weaknesses

-No free tier for SSO or Directory Sync — every enterprise connection costs $100-125/mo
-Smaller ecosystem and community compared to Auth0
-Less mature rules/actions engine for custom login logic

Best for

B2B SaaS companies that need to sell enterprise SSO/SCIM to customers without building it in-house

Auth0

Full-featured identity platform for consumer and enterprise apps

FreeFree up to 25,000 MAUs; Essentials from $35/mo

Strengths

+Mature platform with a large integration and partner ecosystem
+Flexible customization via Actions and Rules for login flows
+Strong consumer (B2C) features: social login, passwordless, breached password detection

Weaknesses

-Pricing jumps sharply once you exceed MAU limits or need enterprise features
-SSO, custom domains, and MFA policies often require higher-priced tiers
-Pricing structure is complex and hard to predict at scale

Best for

Consumer apps or teams that need a mature, highly customizable identity platform and can absorb tiered pricing as they grow

Feature Comparison

SSO (SAML/OIDC) pricing	$125/connection/month	Included only in higher-priced Enterprise plans
SCIM/Directory Sync	$100/connection/month	Enterprise-tier add-on
Social login	Included	Included
MFA	Included	Included, more factor options
Passwordless/magic link	Included	Included
Audit logs	Priced per event	Included in higher tiers
Custom domains	Included free	Requires paid tier
Custom login logic engine	Limited	Actions/Rules — more mature
Self-serve customer SSO setup portal	Built-in Admin Portal	Requires custom build
Pricing model	Per-connection for enterprise features	Per-MAU tiered plans

The Verdict

WorkOS wins for B2B SaaS teams whose main cost driver is selling enterprise SSO to a handful of large customers — its free 1M MAU user management and flat per-connection pricing keep costs predictable. Auth0 is the better choice if you're building a consumer app or need deep customization of login flows, but expect costs and complexity to rise fast once you outgrow the free 25,000 MAU tier.

How to switch from WorkOS to Auth0

1Use the WorkOS Users API (GET /user_management/users) to export all user records as JSON, paginating through results and saving profile data, metadata, and linked SSO connection IDs to a CSV or JSON file.
2Export each SSO/Directory Sync connection's configuration (IdP metadata, SAML certificates, SCIM endpoint URLs) from the WorkOS Dashboard on each connection's settings page.
3Create your Auth0 tenant and use the Auth0 Management API's bulk user import job to load the exported WorkOS users, mapping fields like email, external_id, and any password hashes if applicable.
4Recreate each enterprise customer's SSO connection in Auth0 under Enterprise Connections using the exported IdP metadata and certificates, then have each customer update their IdP's callback/ACS URL to Auth0's endpoint.
5Rebuild any WorkOS-specific functionality — like the self-serve Admin Portal or AuditLogs webhooks — using Auth0 Actions, Rules, and the Organizations feature, testing each customer's login flow individually.
6Run WorkOS and Auth0 in parallel behind a feature flag, migrate a small batch of test users and customers first, verify SSO/MFA flows end-to-end, then cut over remaining traffic and deactivate WorkOS connections.

WorkOS vs Auth0: common questions

How do I export my user data from WorkOS before switching to Auth0?+

Use the WorkOS Users API (GET /user_management/users) to paginate through and export all user records as JSON, including profiles and linked SSO connection metadata. You'll also need to separately export each SSO/SCIM connection's IdP metadata and certificates from the WorkOS Dashboard, since these aren't included in the Users API response.

What features will I lose moving from WorkOS to Auth0?+

You lose WorkOS's built-in Admin Portal, which lets customers self-configure their own SSO/SCIM without your engineering involvement — Auth0 has no direct equivalent, so you'd need to build a similar UI yourself. You may also see a change in pricing behavior since Auth0 charges per MAU rather than per SSO connection.

Is Auth0's free tier enough for a small team already on WorkOS?+

Auth0's free tier caps at 25,000 MAUs with no SSO or custom domains, versus WorkOS's free 1,000,000 MAU limit for basic user management. If your team relies on WorkOS mainly for cheap enterprise SSO connections, Auth0's free tier will likely force you into a paid plan sooner.

Does Auth0 support the same SSO/SCIM integrations WorkOS has already set up with our enterprise customers?+

Yes, Auth0 supports SAML, OIDC, and SCIM through its Enterprise Connections feature, so existing IdP configurations (Okta, Azure AD, Google Workspace, etc.) can be recreated. Each customer will need to update their IdP's callback/ACS URL to point to Auth0, which requires coordination and re-testing per customer.

Will switching from WorkOS to Auth0 cost more or less over time?+

It depends on your mix of MAUs vs. SSO connections: if you have few enterprise customers but many end users, Auth0's per-MAU pricing can work out cheaper. If you have many enterprise SSO customers with low MAU counts, WorkOS's flat per-connection pricing is usually cheaper long-term.
