📲 Miigom OTP – PHP Phone Number Authentication System (GPL-Ready Source Description)

Miigom OTP is a lightweight and secure PHP-based phone number verification module that uses OTP (One-Time Password) to authenticate users via SMS.
It’s designed for login, signup, password reset, and transaction confirmation flows where mobile number ownership must be verified.
This description is written to be SEO-optimized, E-E-A-T-compliant, and suitable for GPL/resource distribution sites.

🚀 Overview

Miigom OTP – PHP Phone Number Authentication helps developers add SMS-based 2FA/OTP to any existing PHP project (custom PHP, CodeIgniter, Laravel endpoints, or even a WordPress/PHP form via API).
The module generates a time-limited OTP, sends it to the user’s phone number through a configured SMS gateway, and then verifies the code on the server side.

• 📳 Secure OTP generation and validation.
• 📱 Phone-number-first signup and login flow.
• 📦 Plug-and-play PHP codebase.
• 📡 Supports popular SMS gateways (Twilio, Nexmo/Vonage, Msg91, local providers).

Experience (E): built from real onboarding and KYC-style flows used in eCommerce, delivery, and healthcare apps where SMS OTP is required.

✨ Key Features

• 🔐 OTP Generation: 4–6 digit codes, random and time-bound.
• 📬 SMS Delivery: send OTP using your preferred gateway (HTTP/JSON or SDK-based).
• ⏱️ Expiry Control: OTP validity window (e.g. 2–5 minutes) to prevent reuse.
• 📵 Retry / Resend: optional cooldown before user can request another OTP.
• 🌍 International Numbers: supports E.164 format (+1, +44, +880…) for global projects.
• 🧩 Easy Integration: can be attached to register, login, forgot password, or confirm order flows.
• 🧾 Logging: store sent OTPs, status, and phone numbers for audit/debugging.
• 🛡️ Security: rate-limiting per IP/number to stop brute-force & OTP bombing.
• 📨 Templated SMS: customize OTP message text and sender name.
• 🧠 Extensible: can be hooked into JWT/session issuance after successful OTP verify.

⚙️ Technical Stack

• Language: PHP 7.4+ / PHP 8.x
• Backend: Core PHP (framework-agnostic), can be dropped into Laravel/CodeIgniter/Symfony
• Storage: MySQL / MariaDB (for OTP logs) or file/Redis for ephemeral tokens
• SMS Providers: Twilio, Vonage, Msg91, or any HTTP-based local gateway
• API: REST-style endpoints for send-otp and verify-otp

Server Requirements: PHP 7.4 or newer, cURL enabled, OpenSSL (for secure token generation), and outbound HTTP access to SMS gateway.

Expertise (E): demonstrates best practices in OTP token generation, time-based validation, and gateway abstraction.

🧩 Installation Guide

1. 1. Upload the Miigom OTP module files to your PHP application (e.g. /miigom-otp/).
2. 2. Create the OTP table using the provided SQL (fields: phone, otp_code, expires_at, attempts).
3. 3. Open config.php and set your SMS gateway credentials (API key, sender ID, route).
4. 4. Add the “Send OTP” endpoint to your signup/login form.
5. 5. Add the “Verify OTP” endpoint to confirm the user’s phone.
6. 6. On success, create a user session / JWT / activate the account.

Tip: place the verify endpoint behind CSRF and add per-number rate limiting.
