What is a free-form gesture password?
Free-form gesture passwords allow you to draw any shape using any number of fingers as your password. It has so far been implemented for touchscreen devices such as smartphones and tablets.
Drawing is more natural and less-demanding than typing on touchscreen devices. Also, previous studies have shown that free-form gesture passwords provide potentially large password space, are resistant against shoulder surfing, and memorable. We believe gesture-based passwords present a strong candidate for alternative authentication mechanisms on mobile platforms.
