Stack Auth

Stack Auth is a complete authentication solution that handles all the complex parts of user login and management. When you add it to your application, you get ready-made login pages, account settings, password reset flows, and user dashboards without writing code for these features yourself.

The platform supports multiple ways for users to sign in, including regular passwords, social logins through Google or GitHub, magic email links, and modern passkeys using fingerprints or face recognition. It also handles advanced features like two-factor authentication for extra security, team management for business apps, and permission systems to control what different users can do.

Stack Auth is fully open-source and licensed under MIT and AGPL, meaning you can see exactly how it works and modify it if needed.

Getting started with Stack Auth is straightforward and quick. Here's how to use it effectively:

• Install the package: Run the setup wizard in your Next.js project, which automatically detects your project structure and configures everything for you.

• Create your account: Visit the Stack Auth dashboard to create a free account and generate your project keys. These keys connect your app to the authentication system.

• Add authentication: Copy the provided environment variables into your project. Stack Auth gives you pre-built React components for login, signup, and account settings that you can drop into your app.

• Customize as needed: Choose which login methods you want (password, Google, GitHub, etc.) from the dashboard. You can also customize the look of the login pages to match your brand.

• Add advanced features: Enable teams, permissions, and webhooks as your app grows. Everything is configured through the simple dashboard interface.
