+
+## 📋 Required Environment Variables
+
+### For AWS Database (Production)
+```env
+# AWS Configuration (for SSM access)
+AWS_REGION=ap-south-1
+AWS_ACCESS_KEY_ID=your_aws_access_key
+AWS_SECRET_ACCESS_KEY=your_aws_secret_key
+USE_AWS_SSM=true
+
+# JWT Configuration
+JWT_ACCESS_SECRET=your_secret
+JWT_REFRESH_SECRET=your_secret
+```
+
+### Optional
+```env
+DB_USE_READONLY=false  # false = read_write_user, true = read_only_user
+DB_HOST=db.livingai.app
+DB_PORT=5432
+DB_NAME=livingai_test_db
+```
+
+## 🔄 Migration Steps
+
+1. **Set up AWS SSM Parameters:**
+   - Create `/test/livingai/db/app` with read-write user credentials (JSON format)
+   - Create `/test/livingai/db/app/readonly` with read-only user credentials (optional)
+
+2. **Update `.env` file:**
+   - Add AWS credentials (AWS_REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY)
+   - Set `USE_AWS_SSM=true`
+   - Remove any database credentials (DB_USER, DB_PASSWORD, DATABASE_URL)
+
+3. **Verify IAM Permissions:**
+   - Ensure IAM user/role has `ssm:GetParameter` permission for both SSM parameter paths
+
+4. **Test Connection:**
+   - Start application: `npm start`
+   - Verify logs show successful SSM credential fetch and database connection
+
+## 🧪 Testing Checklist
+
+- [ ] AWS SSM parameters created with correct paths and JSON format
+- [ ] IAM user has SSM read permissions
+- [ ] `.env` file has AWS credentials (no DB credentials)
+- [ ] `USE_AWS_SSM=true` in `.env`
+- [ ] Application starts without errors
+- [ ] Database connection established successfully
+- [ ] SSL connection working (no SSL errors)
+- [ ] API endpoints respond correctly
+- [ ] Database queries execute successfully
+- [ ] All business logic works as before
+
+## 🔍 Verification Commands
+
+### Check AWS SSM Parameter
+```bash
+aws ssm get-parameter --name "/test/livingai/db/app" --with-decryption --region ap-south-1
+```
+
+### Test Database Connection
+```bash
+npm start
+# Look for these log messages:
+# ✅ Successfully fetched DB credentials from SSM: /test/livingai/db/app (read-write user)
+# ✅ Using database credentials from AWS SSM Parameter Store
+# ✅ Database connection established successfully
+```
+
+## ⚠️ Important Notes
+
+1. **No Breaking Changes**: All business logic remains unchanged. Only database connection configuration was updated.
+
+2. **Backward Compatibility**: Local development still works with `DATABASE_URL` when `USE_AWS_SSM=false`.
+
+3. **Security**: Database credentials are never stored in files. They are fetched from AWS SSM at runtime.
+
+4. **SSL**: Self-signed certificates are supported via `rejectUnauthorized: false` configuration.
+
+5. **Connection Pooling**: Configured with sensible defaults (max 20 connections, 30s idle timeout).

+# AWS Database Migration Guide
+
+This guide explains how to migrate the authentication service from a local Docker PostgreSQL database to an AWS PostgreSQL database using AWS SSM Parameter Store for secure credential management.
+
+## Overview
+
+**Security Model**: Database credentials are fetched from AWS SSM Parameter Store at runtime. NO database credentials are stored in `.env` files or code.
+
+## Prerequisites
+
+1. AWS Account with access to Systems Manager Parameter Store
+2. IAM user/role with permissions to read SSM parameters:
+   - `ssm:GetParameter` for `/test/livingai/db/app`
+   - `ssm:GetParameter` for `/test/livingai/db/app/readonly`
+3. AWS PostgreSQL database instance (RDS or managed PostgreSQL)
+4. Database users created:
+   - `read_write_user` (for authentication service)
+   - `read_only_user` (optional, for read-only operations)
+
+## AWS Configuration
+
+### 1. Set Up AWS SSM Parameters
+
+Store database credentials in AWS SSM Parameter Store as **SecureString** parameters:
+
+#### Read-Write User (Authentication Service)
+**Parameter Path**: `/test/livingai/db/app`
+
+**Parameter Value** (JSON format):
+```json
+{
+  "user": "read_write_user",
+  "password": "your_secure_password_here",
+  "host": "db.livingai.app",
+  "port": "5432",
+  "database": "livingai_test_db"
+}
+```
+
+#### Read-Only User (Optional)
+**Parameter Path**: `/test/livingai/db/app/readonly`
+
+**Parameter Value** (JSON format):
+```json
+{
+  "user": "read_only_user",
+  "password": "your_secure_password_here",
+  "host": "db.livingai.app",
+  "port": "5432",
+  "database": "livingai_test_db"
+}
+```
+
+### 2. Create IAM Policy
+
+Create an IAM policy that allows reading SSM parameters:
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": [
+        "ssm:GetParameter",
+        "ssm:GetParameters"
+      ],
+      "Resource": [
+        "arn:aws:ssm:ap-south-1:*:parameter/test/livingai/db/app",
+        "arn:aws:ssm:ap-south-1:*:parameter/test/livingai/db/app/readonly"
+      ]
+    }
+  ]
+}
+```
+
+Attach this policy to your IAM user or role.
+
+## Environment Variables
+
+### Required Variables
+
+Create or update your `.env` file with **ONLY** these AWS credentials:
+
+```env
+# AWS Configuration (for SSM Parameter Store access)
+AWS_REGION=ap-south-1
+AWS_ACCESS_KEY_ID=your_aws_access_key_here
+AWS_SECRET_ACCESS_KEY=your_aws_secret_key_here
+
+# Enable AWS SSM for database credentials
+USE_AWS_SSM=true
+
+# JWT Configuration (REQUIRED)
+JWT_ACCESS_SECRET=your_jwt_access_secret_here
+JWT_REFRESH_SECRET=your_jwt_refresh_secret_here
+```
+
+### Optional Variables
+
+```env
+# Control which database user to use
+# false = read_write_user (default for auth service)
+# true = read_only_user
+DB_USE_READONLY=false
+
+# Database connection settings (auto-detected if not set)
+DB_HOST=db.livingai.app
+DB_PORT=5432
+DB_NAME=livingai_test_db
+```
+
+### ⚠️ DO NOT Include
+
+**NEVER** include these in your `.env` file:
+- `DB_USER`
+- `DB_PASSWORD`
+- `DATABASE_URL` (with credentials)
+- Any database credentials
+
+Database credentials are fetched from AWS SSM at runtime.
+
+## Database Configuration
+
+### AWS PostgreSQL Settings
+
+- **Host**: `db.livingai.app`
+- **Port**: `5432`
+- **Database**: `livingai_test_db`
+- **SSL**: Required (self-signed certificates supported)
+
+### SSL Configuration
+
+The connection automatically handles SSL with self-signed certificates:
+- `rejectUnauthorized: false` is set for self-signed certificate support
+- Connection string includes `?sslmode=require`
+
+## Migration Steps
+
+### Step 1: Update Environment Variables
+
+1. Remove any existing database credentials from `.env`:
+   ```bash
+   # Remove these if present:
+   # DB_HOST=...
+   # DB_USER=...
+   # DB_PASSWORD=...
+   # DATABASE_URL=...
+   ```
+
+2. Add AWS credentials to `.env`:
+   ```env
+   AWS_REGION=ap-south-1
+   AWS_ACCESS_KEY_ID=your_aws_access_key
+   AWS_SECRET_ACCESS_KEY=your_aws_secret_key
+   USE_AWS_SSM=true
+   ```
+
+### Step 2: Verify SSM Parameters
+
+Ensure your SSM parameters are set correctly:
+
+```bash
+# Using AWS CLI (if configured)
+aws ssm get-parameter --name "/test/livingai/db/app" --with-decryption --region ap-south-1
+```
+
+### Step 3: Test Database Connection
+
+Start your application:
+
+```bash
+npm start
+```
+
+You should see:
+```
+✅ Successfully fetched DB credentials from SSM: /test/livingai/db/app (read-write user)
+✅ Using database credentials from AWS SSM Parameter Store
+   Host: db.livingai.app, Database: livingai_test_db, User: read_write_user
+✅ Database connection established successfully
+```
+
+### Step 4: Run Database Migrations
+
+If you have schema changes, run migrations:
+
+```bash
+node run-migration.js
+```
+
+## Connection Pool Configuration
+
+The connection pool is configured with:
+- **Max connections**: 20
+- **Idle timeout**: 30 seconds
+- **Connection timeout**: 2 seconds
+
+These can be adjusted in `src/db.js` if needed.
+
+## Troubleshooting
+
+### Error: "Cannot access AWS SSM Parameter Store"
+
+**Causes**:
+- Missing AWS credentials in `.env`
+- IAM user doesn't have SSM permissions
+- Wrong AWS region
+
+**Solutions**:
+1. Verify `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` are set
+2. Check IAM permissions for SSM access
+3. Verify `AWS_REGION` matches your SSM parameter region
+
+### Error: "Database connection failed: SSL required"
+
+**Cause**: Database requires SSL but connection isn't using it.
+
+**Solution**: SSL is automatically configured. Verify your database security group allows SSL connections.
+
+### Error: "Parameter not found"
+
+**Cause**: SSM parameter path doesn't exist or has wrong name.
+
+**Solution**:
+1. Verify parameter path: `/test/livingai/db/app`
+2. Check parameter is in correct region
+3. Ensure parameter type is "SecureString"
+
+### Error: "Invalid credentials format"
+
+**Cause**: SSM parameter value is not valid JSON.
+
+**Solution**: Ensure parameter value is JSON format:
+```json
+{
+  "user": "username",
+  "password": "password",
+  "host": "host",
+  "port": "5432",
+  "database": "dbname"
+}
+```
+
+## Local Development
+
+For local development without AWS SSM, you can use `DATABASE_URL`:
+
+```env
+# Disable AWS SSM for local development
+USE_AWS_SSM=false
+
+# Use local database
+DATABASE_URL=postgresql://postgres:password@localhost:5432/farmmarket
+```
+
+**Note**: This should only be used for local development. Production must use AWS SSM.
+
+## Security Best Practices
+
+1. **Never commit `.env` files** - Add `.env` to `.gitignore`
+2. **Rotate credentials regularly** - Update SSM parameters periodically
+3. **Use least privilege** - IAM user should only have SSM read permissions
+4. **Monitor SSM access** - Enable CloudTrail to audit SSM parameter access
+5. **Use different credentials per environment** - Separate SSM parameters for test/prod
+
+## Code Changes Summary
+
+### Files Modified
+
+1. **`src/utils/awsSsm.js`**
+   - Updated to use correct SSM parameter paths
+   - Added support for read-only/read-write user selection
+   - Improved error handling and validation
+
+2. **`src/db.js`**
+   - Added SSL configuration for self-signed certificates
+   - Updated to use `buildDatabaseConfig` instead of connection string
+   - Improved error handling and logging
+
+3. **`src/config.js`**
+   - Removed `DATABASE_URL` from required env vars when using SSM
+   - Added AWS credentials validation
+
+### No Changes Required

+# Database Mode Switch Guide
+
+This guide explains how to switch between **Local Database** and **AWS Database** modes.
+
+## Quick Switch
+
+Add this to your `.env` file to switch between modes:
+
+```env
+# For Local Database (Docker PostgreSQL)
+DATABASE_MODE=local
+
+# For AWS Database (AWS RDS/PostgreSQL with SSM)
+DATABASE_MODE=aws
+```
+
+## Local Database Mode
+
+### Configuration
+
+```env
+# Set database mode
+DATABASE_MODE=local
+
+# Local PostgreSQL connection string
+DATABASE_URL=postgresql://postgres:password123@localhost:5433/farmmarket
+
+# JWT Configuration (required)
+JWT_ACCESS_SECRET=your_jwt_access_secret
+JWT_REFRESH_SECRET=your_jwt_refresh_secret
+
+# Redis (optional)
+REDIS_URL=redis://localhost:6379
+```
+
+### Requirements
+
+- Docker PostgreSQL running (from `docker-compose.yml`)
+- `DATABASE_URL` set in `.env`
+- No AWS credentials needed
+
+### Start Local Database
+
+```bash
+cd db/farmmarket-db
+docker-compose up -d postgres
+```
+
+### Connection String Format
+
+```
+postgresql://[user]:[password]@[host]:[port]/[database]
+```
+
+Example:
+```
+postgresql://postgres:password123@localhost:5433/farmmarket
+```
+
+## AWS Database Mode
+
+### Configuration
+
+```env
+# Set database mode
+DATABASE_MODE=aws
+
+# AWS Configuration (for SSM Parameter Store)
+AWS_REGION=ap-south-1
+AWS_ACCESS_KEY_ID=your_aws_access_key
+AWS_SECRET_ACCESS_KEY=your_aws_secret_key
+
+# Optional: Control which database user
+DB_USE_READONLY=false  # false = read_write_user, true = read_only_user
+
+# Optional: Database connection settings (auto-detected)
+# DB_HOST=db.livingai.app
+# DB_PORT=5432
+# DB_NAME=livingai_test_db
+
+# JWT Configuration (required)
+JWT_ACCESS_SECRET=your_jwt_access_secret
+JWT_REFRESH_SECRET=your_jwt_refresh_secret
+
+# Redis (optional)
+REDIS_URL=redis://your-redis-host:6379
+```
+
+### Requirements
+
+- AWS SSM Parameter Store configured with database credentials
+- AWS credentials (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`)
+- IAM permissions to read SSM parameters
+- AWS PostgreSQL database instance
+
+### SSM Parameter Setup
+
+Store credentials in AWS SSM Parameter Store:
+
+**Path**: `/test/livingai/db/app` (read-write user)
+
+**Value** (JSON):
+```json
+{
+  "user": "read_write_user",
+  "password": "secure_password",
+  "host": "db.livingai.app",
+  "port": "5432",
+  "database": "livingai_test_db"
+}
+```
+
+## Mode Detection Priority
+
+The system determines database mode in this order:
+
+1. **`DATABASE_MODE`** environment variable (highest priority)
+   - `DATABASE_MODE=local` → Local mode
+   - `DATABASE_MODE=aws` → AWS mode
+
+2. **`USE_AWS_SSM`** environment variable (legacy support)
+   - `USE_AWS_SSM=true` → AWS mode
+   - `USE_AWS_SSM=false` or not set → Local mode
+
+3. **`DB_HOST`** auto-detection
+   - `DB_HOST=db.livingai.app` → AWS mode
+   - Otherwise → Local mode
+
+## Examples
+
+### Example 1: Local Development
+
+```env
+# .env file
+DATABASE_MODE=local
+DATABASE_URL=postgresql://postgres:password123@localhost:5433/farmmarket
+JWT_ACCESS_SECRET=dev-secret
+JWT_REFRESH_SECRET=dev-refresh-secret
+REDIS_URL=redis://localhost:6379
+```
+
+**Start services:**
+```bash
+cd db/farmmarket-db
+docker-compose up -d
+```
+
+### Example 2: AWS Production
+
+```env
+# .env file
+DATABASE_MODE=aws
+AWS_REGION=ap-south-1
+AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
+AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
+DB_USE_READONLY=false
+JWT_ACCESS_SECRET=prod-secret
+JWT_REFRESH_SECRET=prod-refresh-secret
+REDIS_URL=redis://your-redis-host:6379
+```
+
+### Example 3: Using Legacy USE_AWS_SSM
+
+```env
+# .env file (still works for backward compatibility)
+USE_AWS_SSM=true
+AWS_REGION=ap-south-1
+AWS_ACCESS_KEY_ID=your_key
+AWS_SECRET_ACCESS_KEY=your_secret
+DATABASE_URL=postgresql://...  # Not used when USE_AWS_SSM=true
+```
+
+## Switching Between Modes
+
+### From Local to AWS
+
+1. Update `.env`:
+   ```env
+   DATABASE_MODE=aws
+   AWS_REGION=ap-south-1
+   AWS_ACCESS_KEY_ID=your_key
+   AWS_SECRET_ACCESS_KEY=your_secret
+   ```
+
+2. Remove or comment out `DATABASE_URL`:
+   ```env
+   # DATABASE_URL=postgresql://...  # Not needed in AWS mode
+   ```
+
+3. Restart application
+
+### From AWS to Local
+
+1. Update `.env`:
+   ```env
+   DATABASE_MODE=local
+   DATABASE_URL=postgresql://postgres:password123@localhost:5433/farmmarket
+   ```
+
+2. Remove or comment out AWS credentials (optional):
+   ```env
+   # AWS_REGION=ap-south-1
+   # AWS_ACCESS_KEY_ID=...
+   # AWS_SECRET_ACCESS_KEY=...
+   ```
+
+3. Start local PostgreSQL:
+   ```bash
+   cd db/farmmarket-db
+   docker-compose up -d postgres
+   ```
+
+4. Restart application
+
+## Verification
+
+### Check Current Mode
+
+When you start the application, you'll see:
+
+**Local Mode:**
+```
+📊 Database Mode: Local (using DATABASE_URL)
+ℹ️  Using DATABASE_URL from environment (local database mode)
+✅ Database connection established successfully
+```
+
+**AWS Mode:**
+```
+📊 Database Mode: AWS (using SSM Parameter Store)
+✅ Successfully fetched DB credentials from SSM: /test/livingai/db/app (read-write user)
+✅ Using database credentials from AWS SSM Parameter Store
+   Host: db.livingai.app, Database: livingai_test_db, User: read_write_user
+✅ Database connection established successfully
+```
+
+## Troubleshooting
+
+### Error: "Missing required environment variables"
+
+**Local Mode:**
+- Ensure `DATABASE_URL` is set
+- Check PostgreSQL is running: `docker-compose ps`
+
+**AWS Mode:**
+- Ensure `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` are set
+- Verify SSM parameters exist in AWS Console
+- Check IAM permissions for SSM access
+
+### Error: "Database connection failed"
+
+**Local Mode:**
+- Verify PostgreSQL is running: `docker ps`
+- Check `DATABASE_URL` format is correct
+- Test connection: `psql postgresql://postgres:password123@localhost:5433/farmmarket`
+
+**AWS Mode:**
+- Verify AWS credentials are correct
+- Check SSM parameter exists and has correct JSON format
+- Verify database security group allows connections
+- Test AWS credentials: `aws ssm get-parameter --name "/test/livingai/db/app" --with-decryption`
+
+## Best Practices
+
+1. **Use `DATABASE_MODE` explicitly** - Most clear and reliable
+2. **Never commit `.env` files** - Keep credentials secure
+3. **Use different `.env` files** - `.env.local` for local, `.env.production` for AWS
+4. **Test both modes** - Ensure your application works in both environments
+5. **Document your setup** - Note which mode each environment uses
+
+## Summary
+
+- **`DATABASE_MODE=local`** → Uses `DATABASE_URL` from `.env`
+- **`DATABASE_MODE=aws`** → Fetches credentials from AWS SSM Parameter Store
+- Both modes work independently
+- Switch by changing one environment variable
+- All business logic remains unchanged

+# Fix Database Permissions Error
+
+## Problem
+
+You're getting this error:
+```
+error: permission denied for schema public
+code: '42501'
+```
+
+This happens because the `read_write_user` doesn't have CREATE permission on the `public` schema.
+
+## Solution
+
+You need to grant permissions using a **database admin/superuser account**. The `read_write_user` cannot grant permissions to itself.
+
+## Option 1: Using Admin Database URL (Recommended)
+
+1. **Get admin database credentials** from your AWS RDS console or database administrator
+   - You need a user with superuser privileges or the schema owner
+
+2. **Add to your `.env` file:**
+   ```env
+   ADMIN_DATABASE_URL=postgresql://admin_user:admin_password@db.livingai.app:5432/livingai_test_db
+   ```
+
+3. **Run the setup script:**
+   ```bash
+   npm run setup-db
+   ```
+
+## Option 2: Manual SQL (If you have database access)
+
+Connect to your database using any PostgreSQL client (psql, pgAdmin, DBeaver, etc.) as an admin user and run:
+
+```sql
+GRANT USAGE ON SCHEMA public TO read_write_user;
+GRANT CREATE ON SCHEMA public TO read_write_user;
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+```
+
+## Option 3: AWS RDS Console
+
+If you're using AWS RDS:
+
+1. Go to AWS RDS Console
+2. Find your database instance
+3. Use "Query Editor" or connect via psql with master credentials
+4. Run the SQL commands from Option 2
+
+## Verification
+
+After running the fix, verify permissions:
+
+```sql
+SELECT 
+  has_schema_privilege('read_write_user', 'public', 'USAGE') as has_usage,
+  has_schema_privilege('read_write_user', 'public', 'CREATE') as has_create;
+```
+
+Both should return `true`.
+
+## Why This Happens
+
+- PostgreSQL doesn't allow users to grant permissions to themselves
+- The `read_write_user` needs CREATE permission to create tables (like `otp_codes`)
+- Only a superuser or schema owner can grant these permissions
+
+## After Fixing
+
+1. Restart your application
+2. Try creating an OTP - it should work now

+# How to Get Admin Database Credentials
+
+## For AWS RDS Databases
+
+### Option 1: AWS RDS Master User (Easiest)
+
+The **master user** created when you set up the RDS instance has superuser privileges.
+
+1. **Go to AWS RDS Console**
+   - Navigate to: https://console.aws.amazon.com/rds/
+   - Select your database instance
+
+2. **Find Master Username**
+   - In the instance details, look for "Master username"
+   - This is usually `postgres` or a custom name you set
+
+3. **Get Master Password**
+   - If you forgot it, you can reset it:
+     - Select your instance → "Modify" → Change master password
+     - Or use AWS Secrets Manager if configured
+
+4. **Use in .env:**
+   ```env
+   ADMIN_DATABASE_URL=postgresql://master_username:master_password@db.livingai.app:5432/livingai_test_db
+   ```
+
+### Option 2: AWS RDS Query Editor
+
+If you have AWS Console access:
+
+1. Go to RDS Console → Your Database → "Query Editor"
+2. Connect using master credentials
+3. Run the SQL commands directly:
+   ```sql
+   GRANT USAGE ON SCHEMA public TO read_write_user;
+   GRANT CREATE ON SCHEMA public TO read_write_user;
+   CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+   ```
+
+### Option 3: Store Admin Credentials in AWS SSM
+
+If you want to automate this:
+
+1. **Store admin credentials in AWS SSM Parameter Store:**
+   ```bash
+   aws ssm put-parameter \
+     --name "/test/livingai/db/admin" \
+     --type "SecureString" \
+     --value '{"user":"admin_user","password":"admin_password","host":"db.livingai.app","port":"5432","database":"livingai_test_db"}' \
+     --region ap-south-1
+   ```
+
+2. **Or set the parameter path in .env:**
+   ```env
+   AWS_SSM_ADMIN_PARAM=/test/livingai/db/admin
+   ```
+
+3. **Run the setup script:**
+   ```bash
+   npm run setup-db
+   ```
+
+### Option 4: Use psql Command Line
+
+If you have psql installed and network access:
+
+```bash
+psql -h db.livingai.app -p 5432 -U master_username -d livingai_test_db
+```
+
+Then run:
+```sql
+GRANT USAGE ON SCHEMA public TO read_write_user;
+GRANT CREATE ON SCHEMA public TO read_write_user;
+CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+```
+
+## For Local Docker Databases
+
+If using local Docker PostgreSQL:
+
+```env
+ADMIN_DATABASE_URL=postgresql://postgres:password123@localhost:5433/farmmarket
+```
+
+The default postgres user has superuser privileges.
+
+## Security Notes
+
+⚠️ **Important:**
+- Never commit admin credentials to git
+- Use AWS SSM Parameter Store or AWS Secrets Manager for production
+- Rotate admin passwords regularly
+- Use the admin account only for setup/maintenance, not for application connections
+
+## After Getting Credentials
+
+1. Add to `.env`:
+   ```env
+   ADMIN_DATABASE_URL=postgresql://admin:password@host:port/database
+   ```
+
+2. Run setup:
+   ```bash
+   npm run setup-db
+   ```
+
+3. Restart your application

+# Quick Fix: Database Permissions
+
+## Current Situation
+
+✅ You can fetch credentials from AWS SSM:
+- `read_only_user` - Read-only access
+- `read_write_user` - Read-write access (but can't grant permissions to itself)
+
+❌ You need **admin/master user** credentials to grant CREATE permission
+
+## Solution: Get AWS RDS Master User Credentials
+
+### Step 1: Find Master User in AWS RDS
+
+1. Go to **AWS RDS Console**: https://console.aws.amazon.com/rds/
+2. Click on your database instance (`db.livingai.app`)
+3. Look for **"Master username"** in the instance details
+   - Usually it's `postgres` or a custom name you set during creation
+
+### Step 2: Get or Reset Master Password
+
+**Option A: You know the password**
+- Use it directly
+
+**Option B: You forgot the password**
+1. Select your RDS instance
+2. Click **"Modify"**
+3. Change the master password
+4. Apply changes (may require a maintenance window)
+
+### Step 3: Store Admin Credentials in AWS SSM
+
+Run this command in your farm-auth-service directory:
+
+```bash
+npm run store-admin
+```
+
+When prompted, enter:
+- **Username**: Your RDS master username (e.g., `postgres`)
+- **Password**: Your RDS master password
+- **Host**: `db.livingai.app` (default)
+- **Port**: `5432` (default)
+- **Database**: `livingai_test_db` (default)
+
+This will store credentials at: `/test/livingai/db/admin`
+
+### Step 4: Run Setup
+
+```bash
+npm run setup-db
+```
+
+The script will automatically:
+1. Find admin credentials from SSM
+2. Grant CREATE permission to `read_write_user`
+3. Create the `uuid-ossp` extension
+4. Verify permissions
+
+### Step 5: Restart Application
+
+```bash
+npm start
+```
+
+## Alternative: Manual SQL
+
+If you prefer to run SQL directly:
+
+1. Connect to your database using any PostgreSQL client with master credentials
+2. Run:
+   ```sql
+   GRANT USAGE ON SCHEMA public TO read_write_user;
+   GRANT CREATE ON SCHEMA public TO read_write_user;
+   CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
+   ```
+
+## Why This Is Needed
+
+PostgreSQL security model:
+- Users cannot grant permissions to themselves
+- Only superusers or schema owners can grant CREATE permission
+- The `read_write_user` needs CREATE permission to create tables like `otp_codes`
+
+## Verification
+
+After setup, verify permissions:
+
+```sql
+SELECT 
+  has_schema_privilege('read_write_user', 'public', 'USAGE') as has_usage,
+  has_schema_privilege('read_write_user', 'public', 'CREATE') as has_create;
+```
+
+Both should return `true`.

+# Redis Setup Guide
+
+Redis is used for distributed rate limiting and OTP tracking. It's **optional** - the service will use in-memory rate limiting if Redis is not available.
+
+## Quick Start
+
+### Option 1: Using Docker Compose (Recommended for Local Development)
+
+Redis is already configured in `db/farmmarket-db/docker-compose.yml`. Start it with:
+
+```bash
+cd db/farmmarket-db
+docker-compose up -d redis
+```
+
+Or start all services (PostgreSQL + Redis):
+
+```bash
+docker-compose up -d
+```
+
+Then add to your `.env` file:
+
+```env
+REDIS_URL=redis://localhost:6379
+```
+
+### Option 2: Install Redis Locally
+
+#### macOS (using Homebrew)
+```bash
+brew install redis
+brew services start redis
+```
+
+#### Ubuntu/Debian
+```bash
+sudo apt update
+sudo apt install redis-server
+sudo systemctl start redis-server
+sudo systemctl enable redis-server
+```
+
+#### Windows
+Download and install from: https://github.com/microsoftarchive/redis/releases
+
+Then add to your `.env` file:
+
+```env
+REDIS_URL=redis://localhost:6379
+```
+
+### Option 3: Use Cloud Redis (Production)
+
+For production, use a managed Redis service:
+- **AWS ElastiCache**: `redis://your-elasticache-endpoint:6379`
+- **Redis Cloud**: `redis://user:password@redis-cloud-host:6379`
+- **Azure Cache for Redis**: `redis://your-cache.redis.cache.windows.net:6380?ssl=true`
+
+Add to your `.env` file:
+
+```env
+REDIS_URL=redis://your-redis-host:6379
+# OR with password
+REDIS_URL=redis://:password@your-redis-host:6379
+```
+
+## Environment Variables
+
+### Using REDIS_URL (Recommended)
+
+Single connection string with all details:
+
+```env
+# Without password
+REDIS_URL=redis://localhost:6379
+
+# With password
+REDIS_URL=redis://:password@localhost:6379
+
+# With username and password
+REDIS_URL=redis://username:password@localhost:6379
+
+# With SSL (AWS ElastiCache, etc.)
+REDIS_URL=rediss://your-redis-host:6379
+```
+
+### Using REDIS_HOST and REDIS_PORT
+
+Separate host and port:
+
+```env
+REDIS_HOST=localhost
+REDIS_PORT=6379
+REDIS_PASSWORD=your_password  # Optional
+```
+
+## Verification
+
+### Test Redis Connection
+
+Start your application and look for:
+
+```
+✅ Redis Client: Ready
+```
+
+If Redis is not available, you'll see:
+
+```
+⚠️ Redis not available. Rate limiting will use in-memory fallback.
+```
+
+### Test Redis Manually
+
+```bash
+# Using redis-cli (if installed)
+redis-cli ping
+# Should return: PONG
+
+# Test connection with password
+redis-cli -h localhost -p 6379 -a your_password ping
+```
+
+## Docker Compose Setup
+
+The `docker-compose.yml` file includes Redis:
+
+```yaml
+services:
+  redis:
+    image: redis:7-alpine
+    container_name: farmmarket-redis
+    restart: always
+    ports:
+      - "6379:6379"
+    volumes:
+      - redis_data:/data
+    command: redis-server --appendonly yes
+```
+
+### Start Redis Only
+
+```bash
+cd db/farmmarket-db
+docker-compose up -d redis
+```
+
+### Stop Redis
+
+```bash
+docker-compose stop redis
+```
+
+### View Redis Logs
+
+```bash
+docker-compose logs -f redis
+```
+
+## Production Recommendations
+
+### 1. Use Managed Redis Service
+
+For production, use a managed Redis service:
+- **AWS ElastiCache** (recommended for AWS deployments)
+- **Redis Cloud**
+- **Azure Cache for Redis**
+- **Google Cloud Memorystore**
+
+### 2. Enable Redis Persistence
+
+If using your own Redis instance:
+- Enable AOF (Append-Only File) persistence
+- Configure regular snapshots (RDB)
+- Set up replication for high availability
+
+### 3. Security
+
+- Use password authentication in production
+- Enable SSL/TLS for connections
+- Restrict network access (firewall/VPC)
+- Use IAM roles (for AWS ElastiCache)
+
+### Example: AWS ElastiCache Configuration
+
+```env
+# AWS ElastiCache endpoint
+REDIS_URL=redis://your-cluster.xxxxx.cache.amazonaws.com:6379
+
+# With password
+REDIS_URL=redis://:your-password@your-cluster.xxxxx.cache.amazonaws.com:6379
+
+# With SSL (if enabled)
+REDIS_URL=rediss://your-cluster.xxxxx.cache.amazonaws.com:6379
+```
+
+## Benefits of Using Redis
+
+### Without Redis (In-Memory)
+- ✅ Simple setup
+- ✅ No external dependencies
+- ❌ Rate limits reset on server restart
+- ❌ Not shared across multiple server instances
+- ❌ Limited scalability
+
+### With Redis
+- ✅ Persistent rate limits (survive restarts)
+- ✅ Shared across multiple server instances
+- ✅ Better scalability
+- ✅ Can handle high traffic
+- ❌ Requires Redis setup and maintenance
+
+## Troubleshooting
+
+### Connection Refused
+
+**Error**: `ECONNREFUSED` or `Connection refused`
+
+**Solutions**:
+1. Check if Redis is running: `docker-compose ps` or `redis-cli ping`
+2. Verify Redis port is correct (default: 6379)
+3. Check firewall settings
+4. Verify REDIS_URL or REDIS_HOST is correct
+
+### Authentication Failed
+
+**Error**: `NOAUTH Authentication required`
+
+**Solutions**:
+1. Add password to REDIS_URL: `redis://:password@host:6379`
+2. Or set `REDIS_PASSWORD` environment variable
+3. Verify password is correct
+
+### Timeout Errors
+
+**Error**: Connection timeout
+
+**Solutions**:
+1. Check network connectivity
+2. Verify Redis host and port are correct
+3. Check if Redis is behind a firewall
+4. Increase connection timeout if needed
+
+## Performance Tuning
+
+### Connection Pooling
+
+The Redis client automatically manages connections. Default settings are suitable for most use cases.
+
+### Memory Optimization
+
+If using local Redis:
+
+```bash
+# Set max memory (e.g., 256MB)
+redis-cli CONFIG SET maxmemory 256mb
+redis-cli CONFIG SET maxmemory-policy allkeys-lru
+```
+
+## Monitoring
+
+### Check Redis Stats
+
+```bash
+redis-cli INFO stats
+```
+
+### Monitor Commands
+
+```bash
+redis-cli MONITOR
+```
+
+### Check Memory Usage
+
+```bash
+redis-cli INFO memory
+```
+
+## Next Steps
+
+1. Set up Redis using one of the options above
+2. Add Redis configuration to your `.env` file
+3. Restart your application
+4. Verify connection with `✅ Redis Client: Ready` message
+5. Test rate limiting to ensure it's working
