How to lock a customer account in magento 2

When you work on a project, the client requires you to block a customer account from the backend, the client means preventing them from using their account. Then the customer can't be able to log in to their account. By default, Magento hasn't this functionality. You don't know how to complete this task, you are searching for a good solution. Today I show you the best codes to complete your task.
We have the scenario: We will create a new customer attribute called "Blocked", it will have two options (Yes/No). If this attribute is set to "Yes" when a customer tries to log in, they will get an inform similar to this "Your account is blocked for the security reason, please contact us for details."
