 ## Environment Setup
 Ensure `VITE_API_BASE_URL` is set on the frontend to the URL of the backend service.
+
+### Supabase Environment Variables
+The application requires the following Supabase environment variables in the `/web` directory:
+
+```
+VITE_SUPABASE_URL=your_supabase_project_url
+VITE_SUPABASE_ANON_KEY=your_supabase_anon_key
+VITE_PUBLIC_SITE_URL=https://bhh.icholding.cloud

+Copy `.env.example` to `.env` and fill in your Supabase credentials.
+
+## Supabase Auth QA Checklist
+
+Before deploying to production, ensure all Supabase authentication flows are working:
+
+- [ ] **Sign up with email/password** → role selected → login works
+- [ ] **Forgot password** → email link received → reset password → login works
+- [ ] **Role selected during signup** persists in `profiles.role`
+- [ ] **Route guard redirects** to correct dashboard based on role
+- [ ] **Password reset link** works when opened on mobile
+- [ ] **Environment variables** are set correctly (not committed to repo)
+- [ ] **Supabase Dashboard URL Configuration** is set:
+  - Site URL: `https://bhh.icholding.cloud`
+  - Redirect URLs include `/reset-password` route
+
+## Supabase Dashboard Configuration
+
+**Important**: After merging Supabase integration, configure the following in your Supabase Dashboard:
+
+1. Go to **Authentication** → **URL Configuration**
+2. Set **Site URL**: `https://bhh.icholding.cloud`
+3. Add **Redirect URLs**:
+   - `https://bhh.icholding.cloud`
+   - `https://bhh.icholding.cloud/reset-password`
+   - `http://localhost:5173/reset-password` (for local development)
+
+## Database Migrations
+
+To apply the Supabase database migrations:
+
+1. Install Supabase CLI: `npm install -g supabase`
+2. Link your project: `supabase link --project-ref your-project-ref`
+3. Apply migrations: `supabase db push`
+
+Alternatively, run the SQL in `/supabase/migrations/0001_profiles_rls.sql` directly in the Supabase SQL Editor.

+# Supabase Integration - Implementation Summary
+
+## Overview
+This document summarizes the complete Supabase integration for the BHH application, including setup instructions, testing guidelines, and deployment notes.
+
+## What Was Implemented
+
+### 1. Core Infrastructure
+- **Supabase Client** (`web/src/lib/supabaseClient.ts`): Singleton client with runtime validation
+- **Site URL Config** (`web/src/lib/siteUrl.ts`): Centralized site URL management
+- **Auth Hook** (`web/src/lib/useSupabaseAuth.tsx`): React hook for auth state management
+
+### 2. Authentication Pages
+- **Login** (`web/src/pages/Auth.jsx`): Uses `signInWithPassword()`
+- **Signup** (`web/src/pages/Register.jsx`): Uses `signUp()` with email confirmation and password validation
+- **Password Reset Request** (`web/src/pages/PasswordReset.jsx`): Uses `resetPasswordForEmail()`
+- **Password Reset Flow** (`web/src/pages/ResetPassword.jsx`): NEW page using `updateUser()` to set new password
+
+### 3. Database Schema
+- **Migration File**: `supabase/migrations/0001_profiles_rls.sql`
+- **Profiles Table**: Auto-created on user signup with role field
+- **RLS Policies**: Users can view/update only their own profile
+- **Triggers**: Auto-create profile on signup, auto-update timestamp
+
+### 4. Security Features
+- ✅ No secrets committed (environment variables only)
+- ✅ Runtime validation of required env vars
+- ✅ Password validation (min 6 chars, matching confirmation)
+- ✅ RLS policies on profiles table
+- ✅ Secure password reset flow
+- ✅ No CodeQL security vulnerabilities detected
+
+## Environment Setup
+
+### Required Environment Variables
+
+Create `/web/.env` with:
+
+```bash
+VITE_SUPABASE_URL=your_supabase_project_url
+VITE_SUPABASE_ANON_KEY=your_supabase_anon_key
+VITE_PUBLIC_SITE_URL=https://bhh.icholding.cloud
+```
+
+**Get these values from:**
+1. Go to your Supabase Dashboard
+2. Project Settings → API
+3. Copy "Project URL" and "anon public" key
+
+### Example Files
+- `.env.example` files are committed at root and `/web` level
+- Copy these to `.env` and fill in your values
+
+## Database Setup
+
+### Option 1: Using Supabase CLI (Recommended)
+```bash
+# Install Supabase CLI
+npm install -g supabase
+
+# Link your project
+supabase link --project-ref your-project-ref
+
+# Apply migrations
+supabase db push
+```
+
+### Option 2: Manual SQL Execution
+1. Go to Supabase Dashboard → SQL Editor
+2. Copy contents of `supabase/migrations/0001_profiles_rls.sql`
+3. Execute the SQL
+
+### Verify Migration
+After running migration, verify in Supabase Dashboard:
+- Table Editor → Check `profiles` table exists
+- Authentication → Policies → Verify RLS policies
+
+## Supabase Dashboard Configuration
+
+**CRITICAL**: Configure these settings in Supabase Dashboard:
+
+1. Go to **Authentication** → **URL Configuration**
+2. Set **Site URL**: `https://bhh.icholding.cloud`
+3. Add **Redirect URLs**:
+   - `https://bhh.icholding.cloud`
+   - `https://bhh.icholding.cloud/ResetPassword`
+   - `http://localhost:5173/ResetPassword` (for local dev)
+
+### Email Templates (Optional)
+You can customize email templates in:
+**Authentication** → **Email Templates**
+
+## Testing Guide

+SELECT * FROM pg_catalog.pg_tables WHERE tablename = 'profiles';
+
+-- View all profiles
+SELECT * FROM profiles;
+
+-- Check RLS policies
+SELECT * FROM pg_policies WHERE tablename = 'profiles';
+
+-- Verify triggers exist
+SELECT * FROM information_schema.triggers WHERE trigger_schema = 'public';
+```
+
+## Deployment Checklist
+
+### Pre-Deployment
+- [ ] All environment variables set in deployment platform
+- [ ] Database migration applied in Supabase
+- [ ] Supabase URL configuration set correctly
+- [ ] Email templates reviewed (optional)
+
+### Post-Deployment
+- [ ] Test signup flow on production URL
+- [ ] Test login flow on production URL
+- [ ] Test password reset (receive and use email)
+- [ ] Verify mobile password reset works
+- [ ] Check that profiles are created in database
+- [ ] Verify RLS policies are working
+
+## Troubleshooting
+
+### Build Fails with Missing Environment Variables
+**Error**: "Missing required environment variable: VITE_SUPABASE_URL"
+
+**Solution**: 
+- Ensure `.env` file exists in `/web` directory
+- Check that variables are prefixed with `VITE_`
+- Restart dev server after adding variables
+
+### Password Reset Email Not Received
+**Possible causes**:
+1. Email in spam folder
+2. Supabase Site URL not configured
+3. Redirect URL not whitelisted
+
+**Solution**:
+- Check Supabase Dashboard → Authentication → URL Configuration
+- Verify Site URL matches your domain
+- Add reset URL to redirect URLs list
+
+### Profile Not Created on Signup
+**Possible causes**:
+1. Migration not applied
+2. Trigger not working
+3. RLS policy blocking insert
+
+**Solution**:
+- Verify migration was applied: Check `profiles` table exists
+- Check trigger: Run `SELECT * FROM information_schema.triggers WHERE trigger_schema = 'public';`
+- Check Supabase logs for errors
+
+### User Can't Log In After Password Reset
+**Possible causes**:
+1. User not confirmed email
+2. Password too short
+3. Supabase auth error
+
+**Solution**:
+- Check user status in Supabase Auth → Users
+- Verify password meets minimum requirements (6 chars)
+- Check Supabase logs for authentication errors
+
+### RLS Policy Errors
+**Error**: "new row violates row-level security policy"
+
+**Solution**:
+- Verify user is authenticated
+- Check that RLS policies are correctly set
+- Ensure user ID matches profile ID
+
+## Architecture Notes
+
+### Why Two Auth Providers?
+The app uses both `AuthProvider` (Base44) and `SupabaseAuthProvider` to maintain backward compatibility. This allows:
+- Gradual migration to Supabase
+- Existing features to continue working
+- New features to use Supabase auth
+
+### Role-Based Routing
+After login, users are routed based on their profile role:
+- `client` → ServicePortal
+- `worker` → EmployeeDashboard
+- `employee` → EmployeeSignup (application)
+- `admin` → AdminDashboard
+
+### Profile Management
+Profiles are auto-created by a database trigger when a user signs up. The client can then update the role field to match the selected account type.
+
+## Next Steps (Optional Enhancements)
+
+### 1. Route Guards
+Create protected route components that:
+- Check if user is authenticated
+- Verify user has correct role for page
+- Redirect unauthorized users
+
+### 2. Social Auth
+Add social login providers:
+- Google
+- GitHub
+- Apple
+
+Configuration in: Supabase Dashboard → Authentication → Providers
+
+### 3. Multi-Factor Authentication
+Enable MFA for enhanced security:
+- SMS-based OTP
+- Authenticator apps
+
+Configuration in: Supabase Dashboard → Authentication → Auth Providers
+
+### 4. Session Management
+Implement session timeout and refresh:
+- Auto-refresh tokens
+- Logout on inactivity
+- Remember me functionality
