use Magento\Framework\AppInterface;
try {
 require_once __DIR__ . '/app/bootstrap.php';

 echo 'Autoload error: ' . $e->getMessage();
 exit(1);
        }


        try{
  $bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);
  $objectManager = $bootstrap->getObjectManager();
  $appState = $objectManager->get('\Magento\Framework\App\State');
 
         $customerRepositoryInterface = $objectManager->get('\Magento\Customer\Api\CustomerRepositoryInterface');
         $customerRegistry = $objectManager->get('\Magento\Customer\Model\CustomerRegistry');
         $encryptor = $objectManager->get('\Magento\Framework\Encryption\EncryptorInterface');
                $appState->setAreaCode('frontend');
 
         $customerId = 1; // here assign your customer id
         $password = "custom_password"; // set your custom password
         $customer = $customerRepositoryInterface->getById($customerId); // _customerRepositoryInterface is an instance of          \Magento\Customer\Api\CustomerRepositoryInterface
         $customerSecure = $customerRegistry->retrieveSecureData($customerId); // _customerRegistry is an instance of \Magento\Customer\Model\CustomerRegistry
         $customerSecure->setRpToken(null);
         $customerSecure->setRpTokenCreatedAt(null);
         $customerSecure->setPasswordHash($encryptor->getHash($password, true)); // here _encryptor is an instance of \Magento\Framework\Encryption\EncryptorInterface
         $customerRepositoryInterface->save($customer);
         echo 'Successfully Changes Your Password.';
         }
         catch(\Exception $e){
      print_r($e->getMessage());
           }

That’s it. On successful execution of the script, your customer will able to login their account using the defined password. In such an emergency, resetting the password using PHP script becomes a life savior way for the developer.
