Introduction

A package for Laravel One Time Password (OTP) generator and validation without Eloquent Model, since it done by Cache. The cache connection same as your laravel cache config and it supported: "apc", "array", "database", "file", "memcached", "redis"

This is a fork of SoipoServices/laravel-otp , thanks to SoipoServices for his hard work.

Installation

Install via composer

composer require soiposervices/laravel-otp

Add Service Provider & Facade

For Laravel 5.5+

Once the package is added, the service provider and facade will be auto discovered.

For Laravel 5.2 / 5.3 / 5.4

Add the ServiceProvider to the providers array in config/app.php:

SoipoServices\Otp\OtpServiceProvider::class

Add the Facade to the aliases array in config/app.php:

'Otp' => SoipoServices\Otp\OtpFacade::class

Configuration

Publish config and language file

php artisan vendor:publish --provider="SoipoServices\Otp\OtpServiceProvider"

This package publishes an otp.php file inside your applications's config folder which contains the settings for this package. Most of the variables are bound to environment variables, you may add Key-Value pair to the .env file in the Laravel application.

OTP_FORMAT=numeric
OTP_LENGTH=6
OTP_SENSITIVE=false
OTP_EXPIRES_TIME=15
OTP_ATTEMPT_TIMES=5
OTP_REPEATED=true
OTP_DEMO=false

Usage

Generate OTP

Otp::generate(string $identifier)

• $identifier: The identity that will be tied to the OTP.

Sample

use OTP;

// in controller

$password = Otp::generate('reg:[e-mail]');

This will generate a OTP that will be valid for 15 minutes.

Validate OTP

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

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

Sample

use OTP;

// in controller

$result = Otp::validate('reg:[e-mail]', '123456');

Responses

On Success

{
  "status": true
}

Invalid OTP

{
  "status": false,
  "error": "invalid"
}

Expired

{
  "status": false,
  "error": "expired"
}

Max attempt

{
  "status": false,
  "error": "max_attempt"
}

• Reached the maximum allowed attempts, default 10 times with each identifier

Validate OTP by Laravel Validation

// in a `FormRequest`

use SoipoServices\Otp\Rules\OtpValidate;

public function rules()
{
    return [
        'code' => ['required', new OtpValidate('change-email:[e-mail]')]
    ];
}

// in a controller

$request->validate([
    'code' => ['required', new OtpValidate('change-email:[e-mail]')]
]);

Validate OTP by session id

// Otp class

$result = Otp::validate('123456');

// in a `FormRequest`

use SoipoServices\Otp\Rules\OtpValidate;

public function rules()
{
    return [
        'code' => ['required', new OtpValidate()]
    ];
}

// in a controller

$request->validate([
    'code' => ['required', new OtpValidate()]
]);

• The setting without identifier will automatically use the session ID as the default, and the OTP generation and verification will be completed in same session (browser's cookies).

Advanced Usage

Generate OTP with options

$password = Otp::setLength(8)->setFormat('string')->setExpires(60)->setRepeated(false)->generate('identifier-key-here');

// or array option

$password = Otp::generate('identifier-key-here', [
    'length' => 8,
    'format' => 'string',
    'expires' => 60,
    'repeated' => false
]);

• setLength($length): The length of the password. Default: 6
• setFormat($format): The format option allows you to decide which generator implementation to be used when generating new passwords. Options: 'string','numeric','numeric-no-zero','customize'. Default: "numeric"
• setExpires($minutes): The expiry time of the password in minutes. Default: 15
• setRepeated($boolean): The repeated of the password. The previous password is valid when new password generated until either one password used or itself expired. Default: true

Generate OTP with customize password

$password = Otp::setCustomize('12345678ABC@#$')->generate('identifier-key-here');

• setCustomize($string): Random letter from the customize string

Validate OTP with specific attempt times

$password = Otp::setAttempts(3)->validate('identifier-key-here', 'password-here');

• setAttempts($times): The number of incorrect password attempts. Default: 5

Validate OTP with case sensitive

$password = Otp::setSensitive(true)->generate('identifier-key-here');

// validate

$result = Otp::setSensitive(true)->validate('identifier-key-here', 'password-here');

// in controller

use SoipoServices\Otp\Rules\OtpValidate;

$request->validate([
    'code' => ['required', new OtpValidate('identifier-key-here', ['sensitive' => true])]
]);

• setSensitive($boolean): Requiring correct input of uppercase and lowercase letters. Default: true

Generate OTP with seperate password

$password = Otp::setLength([4,3,4])->setSeparator(':')->generate('identifier-key-here');

Sample password

3526:126:3697

• setLength($array): The length of the password, use array to separate each length.
• setSeparator($string): The separator of the password. Default: "-"

Validate OTP with extra data

$password = Otp::setData(['user_id' => auth()->id()])->generate('login-confirmation');

• setData($var): Allows you to get the extra data of OTP.

// validate

$result = Otp::setDisposable(false)->validate('login-confirmation', 'password-here');

// in controller

use SoipoServices\Otp\Rules\OtpValidate;

$request->validate([
    'code' => ['required', new OtpValidate('login-confirmation', ['disposable' => false])]
]);

• setDisposable($boolean): The disposable of the Otp identifier, the different password is not valid when same identifier password used. Default: true

On Success Response

{
  "status": true,
  "data": [
    "user_id": 10
  ]
}

• When you set disposable to false, you are able support different password with different extra data for different user in the same identifier key of the OTP.

Validate OTP with skip using

// validate

$result = Otp::setSkip(true)->validate('identifier-key-here', 'password-here');

// in controller

use SoipoServices\Otp\Rules\OtpValidate;

$request->validate([
    'code' => ['required', new OtpValidate('identifier-key-here', ['skip' => true])]
]);

• setSkip($boolean): Skip using the password when validate, which means you can reuse the password again. Default: false
• When there is an error response to the form request, it will skip using the password, but remember to OTP::validate(...) in controller.

Delete OTP

Otp::forget('identifier-key-here');

• Delete all password with this specific identifier

Delete specific password

Otp::forget('identifier-key-here', 'password-here');

Reset attempt times

Otp::resetAttempt('identifier-key-here');

Demo password

Add the following Key-Value pair to the .env file in the Laravel application.

OTP_DEMO=true

• Demo mode for development purposes, no need to use real password to validate.
• Default demo password: "1234", "123456", "12345678"
