At present, a smartwatch can authenticate a user by using a nearby phone controlled by the owner of the smartwatch. However, requiring a nearby phone defeats portability. Also, a watch that retains authentication for purposes of payment constitutes a security risk. This disclosure describes techniques that leverage the haptic crown of a smartwatch to enter numbers in a rotary fashion on the smartwatch screen to authenticate the user for payment or contexts where authentication is necessary. Authentication can be retained on the device until the watch is removed.
