If you're switching from Firebase, Cognito, Supabase, Clerk, or a custom auth system to Auth0, this handles the messy parts: bulk user imports with password hashes, gradual lazy migration for active user bases, and updating your API's JWT validation from HS256 to RS256. It detects your existing auth setup first, then walks you through exporting users, importing them to Auth0, and migrating your frontend and backend code with before/after examples for React, Next.js, Vue, Angular, Express, and React Native. The gradual migration strategy is smart, letting you run both systems in parallel while you move users over. Honestly most useful for the framework-specific migration patterns and the JWT validation updates, which are where most teams get stuck.
