Five years after a hack exposed the data of 77 million users, Sony is finally adding two-factor authentication to its PlayStation Network.
The company did not provide details on the new service, but did say it was still under development and would be released at a later date. As passwords fall out of favor as a security construct, the current popular alternative is two-factor authentication, which requires the user have a second factor in order to gain access to a service.
Popular two-factor authentication schemes today include one-time passcodes sent via mobile SMS or to an email address. In addition, some online services, such as Google, are beginning to explore two-factor authentication using technology based on public key cryptography.
