Okta vs Auth0

The honest comparison

Okta and Auth0 are not really competitors, which is the single most useful thing to know before comparing them. Okta acquired Auth0 in 2021 and Auth0 is now a subsidiary of Okta (NASDAQ: OKTA), but the products serve opposite sides of the identity estate. Okta is workforce IAM: your employees, an app catalog, HR-driven lifecycle, and Universal Directory. Auth0 is CIAM: the login screen inside your own product, built for developers.

We score Okta 4.7 and Auth0 4.6, which says both are top-tier in their own category rather than that they are close substitutes. If you compare them feature by feature you will get a meaningless answer, because the features exist for different populations.

The question worth asking is which problem you have. If the users are on your payroll, you want workforce identity. If they are your customers, you want customer identity. Software companies typically end up with both, and that is the normal outcome, not a procurement failure.

When Okta wins

• Workforce SSO and lifecycle for mid-to-large enterprises
• SaaS app catalog breadth, which is Okta's genuine moat: thousands of pre-built integrations you do not have to write
• HR-driven joiner-mover-leaver automation and SCIM provisioning into downstream apps
• Device and network signal feeding access policy across the whole employee estate
• Governance and access reviews on internal access, where Okta ties into the wider Okta Identity Governance line

When Auth0 wins

• Login you embed in your own application, B2C or B2B SaaS
• Developer experience and extensibility, particularly Actions for injecting custom logic into the authentication pipeline
• Protocol breadth for federation, custom database connections, and progressive migration off a legacy store
• Per monthly active user pricing that matches consumer volume rather than headcount
• Support for a dedicated private cloud deployment where data residency requires it

Pricing

These price on different axes, which is another reason a head-to-head is misleading. Okta is per user per month, billed by module, with published list prices for core SKUs and quote-based reality for enterprise deals. The line items (SSO, MFA, Lifecycle Management, Identity Governance) add up quickly, so model the full bundle rather than the SSO line.

Auth0 has a free tier and then per monthly active user tiers that escalate, with B2B organizations, advanced MFA, and enterprise capabilities gated behind higher plans. The escalation between tiers is the thing to model, since crossing a feature boundary can cost more than crossing a volume one. Run both through the TCO calculator at your real numbers.

Verdict

Buy Okta for your employees and Auth0 for your customers, and stop trying to make one do the other's job. If your actual question is which CIAM to embed in your product, the comparison you want is against Auth0's real rivals: see Auth0 vs Clerk, Auth0 vs Stytch, and the best CIAM platforms ranking. If the question is workforce identity, compare against Microsoft Entra and JumpCloud, and use the how to choose an IAM platform guide.
