Adding Auth0 to your v0 app? Let us review it.
Expert review for Auth0 integrations built with v0. We fix v0-generated Auth0 code for security, error handling & production readiness. From $19.
Common v0 issues affecting integrations
No backend or API integration
v0 generates frontend components only. There's no database connection, API routes, authentication, or server-side logic — all of which need to be built separately.
Static mock data instead of real data
Components use hardcoded mock data for display. Connecting them to real APIs requires significant additional work to handle loading states, errors, and data fetching.
Components not connected to state
Interactive elements like forms, filters, and toggles look correct but don't actually do anything. State management needs to be wired up manually.
Auth0 issues we find in v0 apps
Using deprecated auth0-js instead of @auth0/auth0-spa-js
AI tools generate code with the legacy auth0-js library using implicit grant flow, which is insecure and deprecated in favor of Authorization Code with PKCE.
Storing tokens in localStorage
Generated code saves access and refresh tokens in localStorage, making them vulnerable to XSS attacks. Tokens should use in-memory storage or secure HTTP-only cookies.
Callback and logout URLs not configured for all environments
AI tools hardcode localhost callback URLs and forget to configure production URLs in the Auth0 dashboard, causing redirect failures on deployment.

Frequently asked questions
Can you review my v0-built Auth0 integration?
Yes. We regularly audit Auth0 integrations in v0-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Auth0 issues does v0 typically create?
Common issues in v0-generated Auth0 code include: using deprecated auth0-js instead of @auth0/auth0-spa-js, storing tokens in localstorage, callback and logout urls not configured for all environments. We fix all of these in our code review.
How much does it cost to fix my Auth0 integration?
Start with our code audit ($19) to get a complete list of Auth0 issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Auth0 best practices does v0 typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Auth0. Our review checks all of these and provides specific fixes.
