01
Rising Auth0 invoices
B2B features such as SAML SSO and growing monthly active users pushing you into higher plan tiers.
Rising Auth0 costs and redirect-based login flows
Auth0 to Clerk identity migration playbook
Move off per-MAU Auth0 pricing and redirects: export users and password hashes, set up organizations and SSO, and embed sign-in in your own app.
Symptoms
Signs your platform has this problem
If several of these sound familiar, the plan below is where we would start.
02
Off-domain login redirects
Sending users away from your app to a hosted login page.
03
Slow token verification
Cold serverless functions fetching remote JWKS keys to verify tokens.
Remediation plan
How we fix it, step by step
Each phase ends with a measurement, so you can see what changed before the next one starts.
01
User and password hash export
Exporting users and metadata through the Management API, and password hashes through an Auth0 export request.
02
Organizations and roles
Configuring multi-tenant organizations, role-based permissions and SAML SSO connections.
03
UI components
Embedding accessible sign-in and account components directly in your Next.js application.
04
Session and token cutover
Updating API middleware to verify the new session tokens, then retiring Auth0.
Technical checklist
Remediation checklist
What we check before a change goes to production:
- Export user accounts and bcrypt password hashes from Auth0
- Configure B2B organizations and enterprise SAML SSO in Clerk
- Embed accessible sign-in components in the Next.js app
- Verify JWTs locally in backend middleware
What we measure
We take a baseline first and report the same measurements after each change, from your own monitoring — evidence, not promised results.
- Monthly cost
- Auth0 invoice vs the new provider at your MAU count
- Login success
- Sign-in success rate before and after cutover
- Forced resets
- Users who needed a password reset, tracked daily

Questions about this remediation
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.
