auth0-migration

What problem does it solve?

This Skill eliminates uncertainty when migrating from an existing authentication provider to Auth0 by guiding you through exporting legacy users, importing them safely, and updating the downstream code and JWT validation rules.

Core Features & Use Cases

• Bulk User Export & Import: Covers exporting from Firebase, Cognito, Supabase, Clerk, or custom stores plus running the Auth0 User Import job with required metadata.
• Code Migration Patterns: Points to framework-specific before/after guides for React, Next.js, Vue, Angular, React Native, Express, and backend JWT validation so you can swap SDKs and guard clauses with confidence.
• Gradual Migration Strategy: Recommends phased approaches that run legacy and Auth0 providers in parallel, lazy-migrate active users, and finally drop the old system while keeping JWT validation updated.
• Use Case: When a SaaS app still authenticates through Firebase but needs to shift to Auth0 without disrupting thousands of active users, follow the bulk export, lazy migration, and JS/Express code migration steps laid out here.
