Abstract
A voice key includes a voice sensor, a microprocessor chip, a storage device, a port, a record button, and an enter button. When the voice key is connected to a computing device and the record button is pressed, the voice sensor is triggered to record a voice signal input by a user. The microprocessor chip converts the voice signal into a password, stores the password in the storage device, and sends the password to the computing device to lock the computing device. When the voice key is connected to the computing device again and the enter button is pressed, the microprocessor chip retrieves the password from the storage device and sends the password to the computing device. The computing device is unlocked in response to determining that the received password matches the password stored in the computing device.
