## What it is
useAuth is a React hook library that adds authentication to React apps with minimal setup, supporting Auth0 and Netlify Identity via a provider abstraction and XState-based state management. It exposes a simple useAuth() API for login, signup, logout, session checks, and role/scope-based authorization.

## Use cases
- add authentication to a React app
- add login and signup to a Gatsby site
- handle auth in a Next.js app
- use Auth0 with a React hook
- use Netlify Identity for zero-config login
- check user roles and scopes in React components
- manage auth state with a state machine

## When to choose
- you use React with Gatsby, Next.js, or React Router and want quick Auth0 or Netlify Identity integration
- you want a minimal hook-based auth API with built-in role/scope checks
- you need SSR-safe authentication in a React app

## When to avoid
- you use a provider other than Auth0 or Netlify Identity and don't want to write a custom provider wrapper
- you need server-side or cookie/session-based authentication out of the box
- you need a library with frequent updates and active maintenance

## Facets
- artifact type: library
- maturity: maintenance
- function: auth, authorization, middleware
- domain: web-development, frontend, security, developer-tools
