Development Authentication Bypass

This document explains how to safely disable authentication during development.

🔐 Security Overview

The authentication bypass is designed with multiple layers of security:

Development Mode Only: Only works when vite dev is running
Explicit Opt-in: Requires setting DEV_DISABLE_AUTH=true
Production Protection: Build fails if enabled in production mode
Environment Isolation: Uses local environment files (gitignored)

🚀 Usage

1. Create Local Environment File

Create .env.local (this file is gitignored):

# Copy from example
cp .env.local.example .env.local

2. Enable Development Bypass

Edit .env.local and set:

DEV_DISABLE_AUTH=true

3. Start Development Server

pnpm run dev

You'll see a warning in the console:

🚨 AUTH DISABLED: Development mode with DEV_DISABLE_AUTH=true

4. Access Protected Routes

Protected routes (/rezepte/edit/*, /rezepte/add) will now be accessible without authentication.

🛡️ Security Guarantees

Production Safety

Build-time Check: Production builds fail if DEV_DISABLE_AUTH=true
Runtime Check: Double verification using dev flag from $app/environment
No Environment Leakage: Uses process.env (server-only) not client environment

Development Isolation

Gitignored Files: .env.local is never committed
Example Template: .env.local.example shows safe defaults
Clear Warnings: Console warns when auth is disabled

🧪 Testing the Security

Test Production Build Safety

# This should FAIL with security error
DEV_DISABLE_AUTH=true pnpm run build

Test Normal Production Build

# This should succeed
pnpm run build

🔄 Re-enabling Authentication

Set in .env.local:

DEV_DISABLE_AUTH=false

Or simply delete/rename the .env.local file.

⚠️ Important Notes

Never commit .env.local to git
Never set DEV_DISABLE_AUTH=true in production environment
The bypass provides a mock session with rezepte_users group access
All other authentication flows (signin pages, etc.) remain unchanged
