Pass the password pill

Ever struggled to remember your long, complicated passwords? Or do you just prefer to skip the headache and set them all to your date of birth or the name of your pet?

The average person needs to remember 10 individual PIN codes or passwords a day. One in three people write their passwords down (defeating the purpose of a "secret code") while another one in three of us forget them completely.

Well, that could change in the future; we might be able to get access to our phones, computers, front doors and cars by simply touching them.

At the recent All Things Digital D11 conference, Motorola announced that it has been working on a pill that makes it unnecessary for us to remember passwords at all.

Here is how it works: after a person swallows the "vitamin authentication" pill, the stomach acts as an electrolyte in the chip's battery and powers it. Then the whole body turns into an authentication token that can open any locked device.

This sounds like a magical idea, but there's one potential pitfall. If you buy this pill, how can you be sure that it won't accidentally fall into the wrong stomach?
