MetaPass has designed the M500 Digital Key that allows you to automatically login to any web site, application or terminal without having to type in or remember your password. At first this sounds a bit scary, trusting all your passwords on a single device, but who other than the government could crack 448-bit Blowfish encryption?

The feature I like best is the backup solution, if and when you loose your MetaPass, you will be able to import the backed up data to a new MetaPass to access your accounts again.

A promo is going on right now for September, get $30 off if you enter code m500launch on the website when ordering, the M500 with 16MB extra file storage normally goes for $99.
