Setup

Enable OTP Email Login

  4. Configure your SMTP server settings (required)
  5. Click "Save Changes"

Enable OTP Login

SMTP Configuration Required

You must configure your own SMTP server to send OTP emails:

{
  "host": "smtp.gmail.com",
  "port": 587,
  "secure": false,
  "auth": {
    "user": "your-email@gmail.com",
    "pass": "your-app-password"
  },
  "from": {
    "name": "Your Store Name",
    "email": "your-email@gmail.com"
  }
}

Gmail SMTP: - Host: smtp.gmail.com - Port: 587 - Requires App Password (not your regular Gmail password)

SendGrid SMTP: - Host: smtp.sendgrid.net - Port: 587 - Use API key as password

Other providers: Most email providers offer SMTP services. Check your provider's documentation for settings.
