Adding Apple Sign In to your v0 app? Let us review it.
Expert review for Apple Sign In integrations built with v0. We fix v0-generated Apple Sign In 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.
Apple Sign In issues we find in v0 apps
Client secret JWT generation incorrect
AI-generated code fails to generate the JWT client secret correctly, missing required claims (iss, aud, sub), using the wrong signing key format, or setting incorrect expiry times.
Not handling private email relay addresses
Generated code assumes real email addresses but Apple's Hide My Email feature returns relay addresses (@privaterelay.appleid.com) that AI tools don't account for when sending emails.
Identity token not validated server-side
AI tools trust the identity token from the client without verifying it against Apple's public keys, allowing forged authentication claims.
