Abstract

The present application discloses a control method and device. The method includes: in response to a first startup instruction of an electronic device, when the first system of the electronic device has a first password, output a first interface, the first interface corresponds to In the first system; obtaining first input data, the first input data is input data generated by the user performing an input operation on the first interface; combining the first input data with the first password Perform a comparison to obtain a first comparison result; when the first comparison result indicates that the first password verification is passed, control the first system to enter the startup state; the first system is the electronic A basic system that can be started by the second system of the device; when the first system is in the started state and it is determined that the first comparison result indicates that the first password verification is passed, control the second system of the electronic device The second system enters the startup state.

Description

technical field [0001] The present application relates to the technical field of system control, and in particular, to a control method and device. Background technique [0002] In order to ensure computer data security, a basic input output system BIOS (Basic Input Output System) power-on password and an operating system (operating system) login password are usually set for the computer. [0003] Therefore, the user is usually required to enter the password twice each time the computer is powered on, thereby resulting in a slow boot rate. SUMMARY OF THE INVENTION [0004] In view of this, the present application provides a control method and device, including: [0005] A control method comprising: [0006] In response to the first activation instruction of the electronic device, in the case that the first system of the electronic device has a first password, output a first interface, where the first interface corresponds to the first system; [0007] obtaining first in...
