# 1997 Authenticate A User In A Workflow With Openid Connect

This workflow implements a secure OAuth 2.0 authentication flow, allowing users to log in to your application using an external identity provider.

Example: A web application that needs to authenticate users can use this workflow to integrate with an identity provider like Keycloak or Azure AD. Users can log in to the application using their existing credentials, and the workflow handles the necessary OAuth 2.0 handshake to obtain an access token for the user's profile information.

## What You Can Do
- Supports both PKCE (Proof Key for Code Exchange) and traditional OAuth 2.0 flows
- Retrieves user profile information from the identity provider's userinfo endpoint
- Provides a customizable login page and welcome page for the authenticated user
- Handles the complete OAuth 2.0 authorization code flow, including token exchange and error handling

## Quick Start
1. Import this workflow to n8n
2. Configure your settings
3. Start automating!

⚠️ WARNING: Stop Building Basic Automations For Peanuts. 🚫

Here's the painful truth most won't tell you...

While 90% of builders are stuck selling $500 n8n workflows (and working way too hard)...
I'm consistently closing $6k-13k deals by doing ONE thing differently:
I combine simple automations with custom AI that takes less than a week to build.

Recent client wins:
* Turned a basic invoicing headache into a $6k project that saves my client 20 hours/week
* Built a lead generation machine for law firms - they happily paid $13k (and it runs 24/7)
* Created AI-powered SEO automation that beats funded companies (using $0 in AI costs)

Time to build each solution? Under 2 hours.

But here's what's crazy...
Most automation builders think AI is "too complex" or "too expensive" to add to their stack.
(Meanwhile, I'm charging 10x more for solutions that take the same time to build)

Want to see exactly how I do it?
Inside our community, I show you:
