If I told you this was a piece of military hardware, what would you think it could be? A pocket-sized phaser, perhaps? The remote control for a bomb-disposal robot? Well no, nothing so exciting I'm afraid; it's actually a password manager. Yeah, I know, talk about disappointment.
The culmination of three years development and trialling in-the-field, the Mandylion can store up to 50 log-ins, security codes, safe combinations or passwords, each up to 14 characters in length. It suggests automatically when changing your code might be wise, and can also generate enterprise-grade passwords on demand.
It's $49.99 from ThinkGeek.
