How to update the customer information in Magento 2 (Code to set data for customer).
Example: Update email_backup column of customer_entity table.

  • Within Magento or outside Magento? Which information? – Ankit Shah Dec 20 '16 at 7:49

The email_backup is the custom customer attribute. We can use Magento\Customer\Api\CustomerRepositoryInterface to save the customer info.

 * @var CustomerRepositoryInterface
protected $customerRepository;

public function __construct(

    CustomerRepositoryInterface $customerRepository

    $this->customerRepository = $customerRepository;

We can save:

$customer = $this->customerRepository->getById($customerId);

$customer->setCustomAttribute('email_backup', $emailBackupData);
