For this we need to modify the error message for the required section and for rest leave same as like that by adding condition.
_.extend(GlobalViewsMessageView.prototype, {
getContext: _.wrap(GlobalViewsMessageView.prototype.getContext, function (fn) {
var context = fn.apply(this, _.toArray(arguments).slice(1));
// Modify the context only for the login/register page
var loginElement = document.querySelector('.login-register-login-submit');
if(loginElement){
context.message = "Incorrect email or password. Please correct your email and password."
}
else{
console.log('error');
}
return context;
})
});
