//if User not download private key than update username and email with timestamp.so user not able to do login again.

//Issue with below code: Works fine with new registed user.But It also update existing user's username and email.If not downloded private key.

//check new address == old address[If user do registration in this case this both address are same] and user not downloaded private key

$user = $this->web_model->checkUser($userData);
