If you’re of the paranoid-forgetful type you might want the SpalshID Key Safe. It’s a USB drive with 2GB of storage that contains SpalshID’s software that encrypts all of your passwords, credit card numbers, registrations codes, PINs and more. It can also generate random passwords to dupe any would be hackers from stealing your login information. Just plug it into the computer, do your business, unplug and there won’t be a trace of any of your private info.
It’s both Mac and PC compatible and costs $30.
