Step-by-step

Create an Auth0 application

Configure the app type, callback URLs, and logout URLs that match your Evonx preview and production hosts.

Choose session strategy

Decide cookie sessions vs token handling for SPAs and APIs before wiring SDKs.

Protect server routes

Validate JWTs or session cookies on APIs; map Auth0 user IDs to local profiles.

Map roles and permissions

Use Auth0 roles/RBAC or custom claims and enforce them in your own authorization layer.

Add social or enterprise connections

Enable Google, SAML, or OIDC connections only after base email/password or passwordless works.

Preview login end-to-end

Test signup, login, and forbidden routes in preview, then merge via pull request.

Outcome

Auth0-secured application routes with user mapping and role enforcement you can preview and ship.

FAQ

Auth0 vs Clerk—which guide?

Use Auth0 for enterprise IdP flexibility. Use the Clerk multi-tenant guide when org-first B2B SaaS is the priority.

Where should roles live?

Auth0 can issue claims, but enforce permissions in your API so authorization stays auditable in your DB.

How do preview environments work with callbacks?

Register preview URL patterns in Auth0 allowed callbacks or use a stable auth tunnel domain.
