It is not only the weak memory power that causes the loss of the password. One may take sufficient care to not forget the password, and still the loss of the password cannot be fully avoided. What can an email user do when the hackers hack the account and change the password? Well, there would be no other alternative but to recover the password. And, without the recovery email address or the phone number, it can be very much difficult to recover the password. It is not at all a difficult task to setup the recovery email address or the phone number.
