Abstract

The utility model relates to a device and a method to remove the original password of an electronic device, which comprises a random number generator which generates a random code, a receiving interface which receives an input password and a processing unit which is used to judge whether the input password is corresponding to the random code, and if the input password is corresponding to the random code the original password is removed. The method of the utility model comprises the steps operated by the device.

Description

technical field [0001] The present invention relates to a device and a method for unlocking an original password; in particular, it relates to a device and a method for unlocking an original password by using a random code generated by a random number generator. Background technique [0002] Many current electronic devices, such as projectors, are equipped with power-on password settings to prevent unauthorized users from operating the electronic devices. Users must enter the correct password before they can use these electronic products to achieve the purpose of anti-theft and property management. When the user loses the password, he must try to release the previously set password before he can use it. Therefore, how to unlock the originally set password when the user loses the password is a problem that technicians need to face when designing such electronic devices. [0003] The existing methods for canceling the set original password can be mainly divided into two cate...
