Motorola has announced big plans for replacing your online and device passwords that include taking a pill every morning and wearing a tattoo on your arm.

The two experimental prototypes were showcased during the D11 technology conference by Motorola’s head of advanced technology and projects group, Regina Dugan.

Both concepts are meant as alternatives to using passwords, passcodes, picture passwords, and two-factor authentication as a means to access your smartphone, tablet, car, and even your front door.

The first project Dugan displayed was a simple electronic tattoo manufactured by Cambridge, Massachusetts-based company MC10.

The material can stretch up to 200 percent larger than its original size and features an antenna and a handful of sensors to authenticate with your devices.

“It may be true that ten to twenty year-olds don’t want to wear a watch on their wrist,” Dugan said, taking an obvious dig at the recent rumors surrounding an Apple smart watch. “But you can be sure that they’ll be far more interested in wearing an electronic tattoo, if only to piss off their parents.”

For those who prefer not to have a visible password tattoo, Motorola also plans to develop a form of “vitamin authentication.” Users would take a daily pill, activated by stomach acid, that would send out a 18-bit, ECG-like signal, Dugan said.

“Essentially, your entire body becomes your authentication token,” Dugan explained.

Dugan said the small capsule was developed for medical applications and has been approved by the Food and Drug Administration. Motorola CEO Dennis Woodside said the product has been tested, and has successfully authenticated a smartphone. However, Woodside added, the device isn’t going to ship anytime soon.

While the discussion moderator questioned whether Google, which owns Motorola, will know everything a user is doing, Dugan noted that the company will only know if the pill is turned on or off.
