SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @supabase/supabase-js, and includes scripts (resource) components.

What problem does it solve?

Supabase Auth removes the complexity of implementing and maintaining authentication and session management by providing ready-made email/password sign-up and sign-in, social OAuth, magic links, phone OTP, and JWT-backed sessions that integrate with Postgres Row Level Security.

Core Features & Use Cases

  • Email/password registration and login with optional email confirmation and user metadata.
  • OAuth provider support for Google, GitHub, Apple, Discord and more, including redirect and PKCE handling.
  • Passwordless magic links and phone OTP, automatic token refresh, server-side getUser verification, and RLS-compatible JWTs for protecting routes and enforcing per-user access policies.
  • Use Case: Add a complete auth flow to a Next.js app that supports Google sign-in, email magic links, server-side session validation, and RLS-based data access.

Quick Start

Use the auth skill to add email/password sign-up, Google OAuth, magic-link login, and server-side getUser verification to your application.

FAQPage Schema
How do I add Supabase authentication with OAuth and magic links to my web app?

Add Supabase authentication to implement OAuth, magic links, and email/password login. It handles PKCE exchange and redirects, providing JWT-backed sessions to protect routes and manage user access.

How does Supabase handle server-side session validation and token refresh?

Supabase session validation uses server-side getUser verification and automatic token refresh. It generates RLS-compatible JWTs, ensuring secure per-user data access policies are enforced across web and server contexts.

Can I use Supabase auth for passwordless login with phone OTP?

Yes, Supabase auth supports passwordless login via phone OTP and email magic links. This removes password management complexity while maintaining secure, JWT-backed session handling for your application users.

Does Supabase auth work with Next.js for protecting routes and Row Level Security?

Yes, Supabase auth works with Next.js to protect routes using RLS-compatible JWTs. You can implement Google sign-in, server-side session validation, and automatic token refresh for secure data access.

What is the best way to manage JWT sessions with Supabase and Postgres Row Level Security?

The best way to manage JWT sessions with Supabase is using its built-in auth, which generates RLS-compatible JWTs. This enforces per-user access policies directly in Postgres without custom token logic.

Why does my Supabase OAuth redirect fail during token exchange?

OAuth redirect failures during token exchange often stem from incorrect PKCE handling. Supabase auth manages PKCE exchange and redirect flows automatically, preventing callback errors in social login integrations.
