In a day and age where more and more internet accounts are liable to be hacked, it would be very useful to implement a system such as that used by Gmail and Facebook, which allows users to confirm their access by verifying themselves using a unique, short term code, sent to a designated number using SMS. 10 further codes are given in case the phone is lost, to ensure that the account holder is secure. A password is still used to automatically access an account, and certain IPs may be designated to be allowed without SMS confirmation.
