Magento 2.1 – How to Generate Random Password for Customer

customermagento-2.1password

We had a method to generate the random passwords for the customers in Magento1 in following class.

app\code\core\Mage\Customer\Model\Customer.php

method >>

 /**
     * Retrieve random password
     *
     * @param   int $length
     * @return  string
     */
    public function generatePassword($length = 8)
    {
        $chars = Mage_Core_Helper_Data::CHARS_PASSWORD_LOWERS
            . Mage_Core_Helper_Data::CHARS_PASSWORD_UPPERS
            . Mage_Core_Helper_Data::CHARS_PASSWORD_DIGITS
            . Mage_Core_Helper_Data::CHARS_PASSWORD_SPECIALS;
        return Mage::helper('core')->getRandomString($length, $chars);
    }

What is the similar method in Magento2?

I used the following code to generate the passwords for the customers.

<?php
namespace Muk\Common\Helper;

class CustomerPasswordGeneration extends \Magento\Framework\App\Helper\AbstractHelper
{

    /**
     * @var \Magento\Framework\Math\Random
     */
    protected $mathRandom;

    public function __construct(
        Context $context,
        \Magento\Framework\Math\Random $mathRandom
    ) {        
        $this->mathRandom = $mathRandom;
        parent::__construct($context);
    }

    /**
     * Retrieve random password
     *
     * @param   int $length
     * @return  string
     */
    public function generatePassword($length = 10)
    {
        $chars = \Magento\Framework\Math\Random::CHARS_LOWERS
            . \Magento\Framework\Math\Random::CHARS_UPPERS
            . \Magento\Framework\Math\Random::CHARS_DIGITS;

        return $password = $this->mathRandom->getRandomString($length, $chars);
    }

Magento – How to generate random password for new customer while creating account in magento

You can make the password input in the registration and checkout process as a hidden input and have an algorithm that generates random values for it.
For example at registration you have these fields for passwords

<input type="password" name="password" id="password" title="<?php echo $this->__('Password') ?>" class="input-text required-entry validate-password" />

and

<input type="password" name="confirmation" title="<?php echo $this->__('Confirm Password') ?>" id="confirmation" class="input-text required-entry validate-cpassword" />

Turn them into this:

<?php $password = Mage::helper('core')->getRandomString($length = 7)?>

<input type="hidden" name="password" id="password" title="<?php echo $this->__('Password') ?>" class="input-text required-entry validate-password" value="<?php echo $password?>"  />

and

<input type="hidden" name="confirmation" title="<?php echo $this->__('Confirm Password') ?>" id="confirmation" class="input-text required-entry validate-cpassword" value="<?php echo $password?>" />

Magento2 – How to Check if Customer Password Matches

Please check this model

Magento\Customer\Model\Authentication.php

In this You will find one method authenticate($customerId, $password)

    public function authenticate($customerId, $password)
    {
        $customerSecure = $this->customerRegistry->retrieveSecureData($customerId);
        $hash = $customerSecure->getPasswordHash();
        if (!$this->encryptor->validateHash($password, $hash)) {
            $this->processAuthenticationFailure($customerId);
            if ($this->isLocked($customerId)) {
                throw new UserLockedException(__('The account is locked.'));
            }
            throw new InvalidEmailOrPasswordException(__('Invalid login or password.'));
        }
        return true;
    }

You can call this method and pass $customerId, and Password string. If password will be correct then it will return true. Otherwise it will throw an exception.
