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.
