ระบบดั้งเดิมที่ได้รับการพัฒนา (Standard 2FA)

This system is ideal for financial transactions and admin panels. It ensures the user is physically present and performing the action themselves.

Integration Steps:

1. The user enters their regular Password, which is verified on your server.

2. Instead of sending an SMS, call the /api/verify/init endpoint to start a ReOTP session.

3. Show the ReOTP UI prompting the user to send the code via WhatsApp or Telegram.

4. Your front-end starts polling /api/verify/status.

5. Once the server returns VERIFIED, the user is logged in or allowed to proceed with the sensitive transaction.
