Auth0

Identity platform Secure access for everyone. Add authentication and authorization to your apps with social logins, SSO, and MFA.

Key Features

  • Social & enterprise login
  • SSO & MFA
  • Universal Login

Setup

1

Create a tenant

Create a tenant at auth0.com, add an Application (SPA or Regular Web), configure callback URLs.
2

Install SDK

npm install @auth0/auth0-react
3

Configure the SDK

Use Auth0 React SDK or Next.js SDK for minimal setup; Universal Login handles the UI.

Social & features

Enable Google, GitHub, etc. in the Dashboard → Authentication → Social.
MFA and rules are available for production; skip for hackathon MVPs unless needed.

Hackathon tips

  • Free tier includes 7,000 active users; enough for demos and judging.
  • Use the hosted login page to avoid building your own UI—focus on your app.
