Magento 2.3 - Login Authentication not working for validating customer email and password

Question

Hi I have created Rest API for customer login with custom module for my Magento 2.3 store.

I am entering parameters email and password for customer login. But it throws InvalidEmailOrPasswordException while firing api request.

Below is my code:

<?php
use Magento\Customer\Api\AccountManagementInterface;
class CustomerManagement
{
 /**
 * @var Magento\Customer\Api\AccountManagementInterface
 */
 protected $accountManagementInterface;
 protected $customer;
 protected $_customerSession;
 public function __construct(
 \Magento\Framework\App\Action\Context $context,
 AccountManagementInterface $accountManagementInterface,
 \Magento\Customer\Model\Customer $customer,
 \Magento\Customer\Model\Session $customerSession
 ) {
 $this->objectManager = $context->getObjectManager();
 $this->resultPageFactory = $resultPageFactory;
 $this->accountManagementInterface = $accountManagementInterface;
 $this->customer = $customer;
 $this->_customerSession = $customerSession;
 parent::__construct($context);
 }
public function getLogin()
{
 $email = $this->request->getParam('email');
 $password = $this->request->getParam('password');
 try {
 /* @var $customer \Magento\Customer\Api\Data\CustomerInterface */
 $customer = $this->accountManagementInterface->authenticate($email, $password);
 $websiteId = $customer->getWebsiteId();
 /* @var $_customer \Magento\Customer\Model\Customer */
 $_customer = $this->customer->setWebsiteId($websiteId);
 $this->_customerSession->setCustomerAsLoggedIn($_customer->loadByEmail($email)); 
 } catch(\Magento\Framework\Exception\InvalidEmailOrPasswordException $ex) {
 $errorData[0]['code'] = 7;
 $errorData[0]['message'] = 'Invalid Params!';
 $errorData[0]['exception'] = $ex;
 return $errorData;
 }
 .....
}

Here my code throws catch exception even if I use valid email and password for customer login API.

Answer 1

Following code is wrong:

 $customer = $this->accountManagementInterface->authenticate($newLoginValue, $password);

Should be:

 $customer = $this->accountManagementInterface->authenticate($email, $password);

Answer 2

Email ID is missing. Update function as:

public function getLogin()
{
 $email = $this->request->getParam('email');
 $password = $this->request->getParam('password');
 try {
 /* @var $customer \Magento\Customer\Api\Data\CustomerInterface */
 $customer = $this->accountManagementInterface->authenticate($email, $password);
 $websiteId = $customer->getWebsiteId();
 /* @var $_customer \Magento\Customer\Model\Customer */
 $_customer = $this->customer->setWebsiteId($websiteId);
 $this->_customerSession->setCustomerAsLoggedIn($_customer->loadByEmail($email)); 
 } catch(\Magento\Framework\Exception\InvalidEmailOrPasswordException $ex) {
 $errorData[0]['code'] = 7;
 $errorData[0]['message'] = 'Invalid Params!';
 $errorData[0]['exception'] = $ex;
 return $errorData;
 }
 .....
}
