Abstract: A method, an apparatus and a device for sharing a password between a BIOS and an operating system are provided, which are applied to a Legacy boot mode. In the method, a user is prompted to input a password of the BIOS. The password inputted by the logon user is received and verified. The verified password is stored in a predetermined target memory and E820H information is created if the received password is verified as correct, where address data in the E820H information points to an address of the target memory. The address of the target memory is determined based on the created E820H information and memory contents are obtained if a password is set for the operating system. The logon user is permitted to log on the operating system if the acquired memory contents are verified as correct.
