React + FastAPI Authentication Guide

A tutorial demonstrates how to build a React and FastAPI application with user signup, login, account management, profile-picture uploads, Google social login, passwordless authentication, and optional organization support using PropelAuth. PropelAuth supplies hosted, configurable authentication pages and handles features such as transactional emails, two-factor authentication, user metadata, and token management, while React integrates through the @propelauth/react AuthProvider, authentication-aware components, redirect hooks, and access tokens for protected API requests. The FastAPI backend uses the propelauth-fastapi library to validate JWT access tokens through a dependency that protects routes such as a who-am-I endpoint, returning unauthorized responses when no valid token is present. The guide also addresses local cross-origin requests through a React proxy configuration and emphasizes that this approach provides a functional authenticated application with relatively little custom authentication code.
