Supabase Auth

nice-wolf-studio/claude-code-supabase-skills

Handles the full auth lifecycle for Supabase projects through bash scripts: signup, login, token management, password resets, and user CRUD. The examples cover both client-side operations (using access tokens) and admin functions (requiring service role keys), which is helpful since the permission model matters a lot here. You get practical patterns for storing tokens after login and paginating through user lists. The reliance on a shared supabase-api.sh helper keeps things clean, though you'll need to make sure that script exists in your project structure. If you're building CLI tools or automation around a Supabase backend, this gives you the auth primitives without reaching for a JavaScript client.

Supabase Authentication

Overview

This skill provides authentication and user management operations through the Supabase Auth API. Supports email/password authentication, session management, user metadata, and password recovery.

Prerequisites

Required environment variables:

export SUPABASE_URL="https://your-project.supabase.co"
export SUPABASE_KEY="your-anon-or-service-role-key"

Helper script: This skill uses the shared Supabase API helper. Make sure to source it:

source "$(dirname "${BASH_SOURCE[0]}")/../../scripts/supabase-api.sh"

Common Operations

Sign Up - Create New User

Basic email/password signup:

source "$(dirname "${BASH_SOURCE[0]}")/../../scripts/supabase-api.sh"

supabase_post "/auth/v1/signup" '{
  "email": "user@example.com",
  "password": "securepassword123"
}'

Signup with user metadata:

supabase_post "/auth/v1/signup" '{
  "email": "user@example.com",
  "password": "securepassword123",
  "data": {
    "first_name": "John",
    "last_name": "Doe",
    "age": 30
