User Authentication System Skill
Automate setup of complete authentication systems with OAuth, session management, and security best practices.
Purpose
Quickly add production-ready authentication to web applications with support for multiple providers (Clerk, Supabase, Auth0, NextAuth).
When to Use
- Adding auth to a new application
- Switching auth providers
- Implementing OAuth (Google, GitHub, etc.)
- Setting up role-based access control
- Migrating from custom auth
Quick Start
python3 /home/ubuntu/skills/user-authentication-system/scripts/setup_auth.py \
/path/to/project \
clerk \
pk_test_your_key
Supported Providers
- Clerk - Fastest setup (10 min)
- Supabase - Open source, free tier
- Auth0 - Enterprise-grade
- NextAuth - Full control, customizable
What It Does
- Detects framework (Next.js, React, Express, Flask)
- Installs auth dependencies
- Creates configuration files
- Generates auth provider components
- Provides sign-in/sign-up templates
Protected Routes Example
import { auth } from '@clerk/nextjs'
export default async function Dashboard() {
const { userId } = auth()
if (!userId) redirect('/sign-in')
return <div>Protected content</div>
}
Time Savings
Manual: 2-3 hours
With Skill: 15-20 minutes
Saved: ~2 hours per project

VerifiedTrustedCommunity
Generate comprehensive demonstrations showing how to access projects and work across different environments (Manus terminals, personal computers, team collaboration). Use when users ask "how do I access this from another terminal/computer", "how do I share this with my team", "how do I get this on my Mac", or need clarification on Manus persistence vs GitHub usage.
