Last updated February 26, 2024
Introduction
Authentication is a cornerstone of modern web and mobile applications, ensuring that users can securely access their accounts and data. Supabase simplifies the authentication process by providing a powerful, easy-to-implement authentication system that supports everything from email and password login to third-party providers. This guide will walk you through the steps to integrate Supabase Auth into your application, providing your users with a seamless and secure authentication experience.
Step-by-Step Guide
- Set Up Your Supabase Project
- Enable Authentication Methods
- In the Supabase dashboard, go to the "Authentication" section and select "Settings". Here, you can enable various authentication methods, including email/password, magic links, and third-party providers like Google, GitHub, and more.
- Configure Third-party Providers (Optional)
- If you choose to enable third-party authentication, you'll need to set up OAuth credentials with each provider and input these into your Supabase project settings. Each provider has a different setup process, so refer to the Supabase documentation for detailed instructions.
- Install the Supabase Client Library
- Initialize Supabase in Your Application
- Implement Sign Up and Sign In
- Handle Authentication State
- Secure Your Application with Row Level Security
- Enable Row Level Security (RLS) on your database tables to ensure that users can only access data they are permitted to see. This is done directly in the PostgreSQL interface within the Supabase dashboard.
- Test Your Implementation
- Thoroughly test your authentication flow, including sign-up, sign-in, password recovery, and third-party logins, to ensure everything works smoothly and securely.
