ASUS UX21E series security function settings are as follows:

1. Hard drive confidentiality: Users can set their own hard drive password in the Security menu of the BIOS setup program. The hard drive password will be asked during system startup. In this way, when the hard drive is used by others, the hard drive cannot be used or booted without the provided password. This also ensures that the data will not be stolen by others. Even using an external hard drive enclosure cannot circumvent this protection.

2. System confidentiality: You can also set a user password in the Security menu of the BIOS setup program. The system administrator's password will be asked every time you boot or enter the BIOS setup program. . In this way, unauthorized users can be prevented from operating the computer.

If the above two passwords are set, when the system is turned on, it will first ask for the hard disk password and then the system password (the two sets of passwords can be set to different values). Reminder: After setting the password, please keep the password information properly. If you forget it, you must consult the original manufacturer for support.
