PocketStation as two-factor authentication
[DarkFader] sent in his build that implements two-factor authentication on a Sony PocketStation.
The PocketStation was a PS1 accessory intended to be a competitor to the Dreamcast VMU. [DarkFader] wrote an app for his PocketStation using a fabulous PocketStation emulator and uploaded it with the PS3 memory card adapter and MCRWwin.
The PocketStation app (available here) takes a key and hashes it with the current time to generate a six digit code. Combined with Google’s support for two-factor authentication, [DarkFader]‘s memory card provides access to his Google profile.
Two-factor authentication is also used in RSA SecurID key fobs that werecompromised earlier this year. This lead to a huge number of companies being penetrated. For a single person, obscurity is a reasonable (but still ultimately futile) means of providing a little more security, but a PocketStation hack is still pretty cool.
