Migration playbook: Auth0 (Okta) → Clerk or self-hosted auth

Auth0 to Clerk and modern identity migration

Move from per-MAU Auth0 pricing and redirect-based login to developer-first authentication with embedded components and built-in B2B organizations.

Migration drivers

Why teams make this move

Driver 01

Enterprise SSO pricing

B2B features such as SAML SSO tied to higher Auth0 plan tiers.

Driver 02

Redirect-based login

Sending users away from your app to a hosted login page.

Driver 03

Token verification latency

Fetching remote JWKS keys on cold serverless functions.

Execution sequence

How the migration runs

Each phase ends with a check you can verify — data parity, error rates, latency — and the rollback path is agreed before any traffic moves.

  1. 01Phase

    User and password hash export

    Exporting users and metadata through the Management API, and password hashes through an Auth0 export request.

  2. 02Phase

    Organizations and roles

    Configuring multi-tenant organizations, role-based permissions and SAML SSO connections.

  3. 03Phase

    UI components

    Embedding accessible sign-in and account components directly in your Next.js application.

  4. 04Phase

    Session and token cutover

    Updating API middleware to verify the new session tokens, then retiring Auth0.

Risk prevention

Pitfalls that derail this migration

Risk 01

Social login account linking

Not linking existing email and password accounts with their Google or GitHub logins.

Risk 02

Lost Auth0 Actions

Overlooking Auth0 Actions or Rules that add custom claims to tokens.

Risk 03

SAML metadata updates

Forgetting to tell enterprise customers to update their identity provider metadata.

Before and after

What we measure

We take a baseline before any change and report the same numbers after cutover, from your own tools. They are the evidence of whether the migration worked — not figures promised in advance.

Monthly cost

Questions

Frequently asked migration questions

Usually not. Auth0 can export password hashes (bcrypt) on request, and most modern providers import bcrypt hashes directly. We confirm with a sample of users before the cutover.

Clerk has B2B organizations built in, with member invitations, role switching and per-organization SAML SSO.
