Pico: No more passwords!

Passwords are a pain. Pico is a more usable and more secure replacement that does not require you to memorize any secrets.

It consists of a small portable device that stores the user's credentials. The Picosiblings are even smaller wearable accessories that tell the Pico its owner is nearby. The Pico can then automatically log the user in to websites and other protected systems, and log them out again when appropriate.

Why do we need it?
