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

appcodecoreMageCustomerModelCustomer.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 MukCommonHelper;

class CustomerPasswordGeneration extends MagentoFrameworkAppHelperAbstractHelper
{

 /**
 * @var MagentoFrameworkMathRandom
 */
 protected $mathRandom;

 public function __construct(
 Context $context,
 MagentoFrameworkMathRandom $mathRandom
 ) 
 $this->mathRandom = $mathRandom;
 parent::__construct($context);
 

 /**
 * Retrieve random password
 *
 * @param int $length
 * @return string
 */
 public function generatePassword($length = 10)
 
 $chars = MagentoFrameworkMathRandom::CHARS_LOWERS
 . MagentoFrameworkMathRandom::CHARS_UPPERS
 . MagentoFrameworkMathRandom::CHARS_DIGITS;

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

Magento use function like this in the setup script

vendor/magento/magento2-base/setup/src/Magento/Setup/Model/AdminAccount.php

 /**
 * Generate password string
 *
 * @return string
 */
 protected function generatePassword()
 
 return $this->encryptor->getHash($this->data[self::KEY_PASSWORD], true);
 

I have made one custom url (new custom controller) to generate customer's password .

<?php
namespace CompanyModuleControllerIndex;

use MagentoFrameworkEncryptionEncryptorInterface as Encryptor;

class Index extends MagentoFrameworkAppActionAction 

 protected $_resultPageFactory;
 protected $_indexer;

 public function __construct(MagentoFrameworkAppActionContext $context,Encryptor $encryptor, MagentoFrameworkViewResultPageFactory $resultPageFactory) 
 $this->_resultPageFactory = $resultPageFactory;
 $this->encryptor = $encryptor;
 return parent::__construct($context);
 

 public function execute() 
 $password = '123456'; //or you can use php random function rand() to generate string
 $hash = $this->encryptor->hash($password);
 $newhash = $this->encryptor->getHash($password, true);
 echo $newhash; // this will be customer's new password, which need to store in 'password_hash' column of "customer_entity" db table.
 

you can integrate same code in your functional method / file .

I used this code simply and got result

 <?php 
 function generateRandomString($length) 
 $characters = 
 '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ@#$%&';
 $charactersLength = strlen($characters);
 $randomString = '';
 for ($i = 0; $i < $length; $i++) 
 $randomString .= $characters[rand(0, $charactersLength - 1)];
 
 return $randomString;
 
?>

<?php echo generateRandomString(5); ?>

I used the following method

 <?php

 function randomPassword()
 
 $alphabet = "abcdefghijklmnopqrstuwxyzABCDEFGHIJKLMNOPQRSTUWXYZ0123456789";
 $password = [];
 $alphaLength = strlen($alphabet) - 1;
 for ($i = 0; $i < 8; $i++) 
 $n = rand(0, $alphaLength);
 $password[] = $alphabet[$n];
 
 return implode($password);
 

randomPassword();
