To protect the accounts of Twitter has implemented two-factor authentication. For its activation is only necessary to put down the checkbox next to 'Require confirmation code when I log in to Twitter "and be sure to attach to the account number. After switching on the two-stage authorization Twitter will send an SMS PIN.
However, Kim Dotcom said that he invented this method of protection. Now it is used Twitter, Facebook, Google, as well as online banks. The patent for two-factor authentication Dotcom, according to him, allegedly received in 1997. Now he is accused of internet piracy, fraud and money laundering and is under house arrest in New Zealand.
