Hi This case i think you will be having all these details in the database. or you need to store some where to track all these things. The password history last updated password data has to be loaded or querying from the database to validate against in the login form. The client side validation may be not suitable here. Because you shouldn't keep in the browser side for security reasons. Write the server side event to validate against database.
