Introduction 🖖

This is a simple package to generate and validate OTPs (One Time Passwords). This can be implemented mostly in Authentication.

Installation 💽

Install via composer

composer require ichtrojan/laravel-otp

Add service provider to the config/app.php file

<?php
   /*
    |--------------------------------------------------------------------------
    | Autoloaded Service Providers
    |--------------------------------------------------------------------------
    |
    | The service providers listed here will be automatically loaded on the
    | request to your application. Feel free to add your own services to
    | this array to grant expanded functionality to your applications.
    |
    */

    'providers' => [
        ...
        Ichtrojan\Otp\OtpServiceProvider::class,
    ];
...

Add alias to the config/app.php file

<?php

   /*
    |--------------------------------------------------------------------------
    | Class Aliases
    |--------------------------------------------------------------------------
    |
    | This array of class aliases will be registered when this application
    | is started. However, feel free to register as many as you wish as
    | the aliases are "lazy" loaded so they don't hinder performance.
    |
    */

    'aliases' => [
        ...
        'Otp' => Ichtrojan\Otp\Otp::class,
    ];
...

php artisan migrate

Usage 🧨

Generate OTP

<?php

Otp::generate(string $identifier, int $digits = 4, int $validity = 10)

• $identifier: The identity that will be tied to the OTP.
• $digit (optional | default = 4): The amount of digits to be generated, can be any of 4, 5 and 6.
• $validity (optional | default = 10): The validity period of the OTP in minutes.

Sample

<?php

$otp = Otp::generate('[e-mail]', 6, 15);

This will generate a six digit OTP that will be valid for 15 minutes and the success response will be:

{
  "status": true,
  "token": "282581",
  "message": "OTP generated"
}

Validate OTP

<?php

Otp::validate(string $identifier, string $token)

• $identifier: The identity that is tied to the OTP.
• $token: The token tied to the identity.

Sample

<?php

$otp = Otp::validate('[e-mail]', '282581');
