Simon Grimm walks through building a complete authentication system for a mobile app, using JWT (JSON Web Tokens) as the security mechanism behind a members-only experience.

The building blocks

  • How JWTs work, and how to generate and validate them to protect access to sensitive data
  • Building interactive forms with React Hook Form, including clean state handling
  • Validating form input with Zod to keep data integrity intact
  • Managing app data with queries and mutations for smooth reads and updates
  • Wiring it all into a secure authentication flow using the Expo SDK

Across 13 lessons, these pieces come together into one working authentication system, so you finish with a pattern for securing a React Native app rather than isolated demos of each tool.
