Zero-Type Auth (Login Without Number)

Overview

Fastest user login method: Direct WhatsApp/Telegram buttons without number input. The system automatically captures the number from the message.

Implementation

This example uses the same ReOTP API interface:

1. Call POST /api/verify/init with phoneNumber (optional) and method (WHATSAPP/TELEGRAM/PREDICTIVE).

2. Immediately start listening (SSE (Server-Sent Events)) on /api/verify/stream?id=<requestId>.

3. Upon receiving VERIFIED, execute your logic.

UI/UX Guidelines

• Design interface compatible with ReOTP: Dark background (#05050A), Liquid Glass cards with backdrop-blur-xl, white borders/15.

• Display a 120-second countdown to create urgency.

• Use clear single-action buttons (CTA) at each step.

• Support RTL/LTR via dir.
