Auth0

Okta’s Customer Identity (CIAM) product line known as Okta Customer Identity Cloud (powered by Auth0), commonly called Auth0 provides hosted authentication/authorization, user management, federation to enterprise IdPs, and extensibility for consumer and B2B apps.

Key Capabilities

  • Standards-based authentication: OpenID Connect and OAuth 2.0; SAML 2.0 supported both for inbound enterprise federation (Auth0 as SP) and outbound to SAML apps (Auth0 as IdP).

  • MFA & risk: Adaptive MFA (risk-based), multiple factors, and WebAuthn/passkeys support.

  • Enterprise federation: Built-in connections for SAML and OIDC (e.g., Microsoft Entra ID, Okta Workforce); PKCE supported for OIDC enterprise connections.

  • B2B tenant model: Organizations feature for multi-tenant B2B use cases (org-scoped logins, roles, invitations).

  • Hosted login & SDKs: Universal Login with OIDC discovery metadata for app configuration; broad SDK coverage.

Limitations

  • Rules/Hooks deprecated: Legacy extensibility (Rules/Hooks) is deprecated in favor of Actions; complete removal has been postponed with the current EOL listed as November 18, 2026 (prior plan targeted November 18, 2024 with read-only transition).

  • Rate limits apply: Authentication/Management APIs enforce burst/sustained limits that vary by plan and environment. High-volume automations must account for throttling.

  • Embedded/iframe login caveats: Third-party cookie restrictions (e.g., Safari/Chrome ITP) affect silent auth/embedded flows without custom domains or alternate patterns.

  • Feature availability by region/plan: Some capabilities (e.g., Adaptive MFA, Organizations) are plan-gated; endpoints and CDNs vary by selected region.
