Using a BIOS Password

1
Understand what a BIOS password is. A BIOS password is the extremely strong password that locks up the hardware and makes the computer completely unusable. There are two different kinds of BIOS passwords, a User password, and a Supervisor password, their differences are listed below:
- Supervisor password: This is a password that only locks the BIOS configuration menu. You might want to at least set this password and make sure that your hard drive is the first boot device since it will prevent someone from removing your Windows password with a password reset disk.
- User password: This password locks down your whole computer. When you start up your computer the first thing that will come up will be a box asking you to enter this password. You have to enter this password before the computer will start.
2
Open the BIOS. You have to press a button when you see the computer logo at startup to enter the BIOS. The button you press varies by computer manufactures, below are some of the more common ones:
- Dell: F2
- HP: F10
- Lenovo: F1
- Asus: Del
- If these buttons don't work, or if you have a different model, then you can try to search online for the correct way to access your BIOS.
3
Navigate to the Security tab. The tabs will be show near the top and you will typically use the left and right arrow keys to change the tab selection.
4
Decide what password you want to use. Review the differences between the two passwords above and decide which one you want to set, or if you want to set both of them.
5
Enter the password that you want to set. Make sure that you remember this password as it can be difficult to reset it if you forget.
- You might want to write the password down on a piece of paper, and then lock the paper in a safe so that if you ever do forget it, you can still get access to your computer.
6
Head over the Exit tab. Once there, select the option that allows you to save your changes and exit or reset. Once you do that, the BIOS password will be set.

Even if you don't think anyone else is going to use your computer, you never know. What if someone breaks into your home and steals it? If it isn't password-protected, whoever has your computer will have access to all of your personal information.

If you enable the password protection, yes. It shouldn't take you more than a few seconds to enter your password, though. It's worth it for a little peace of mind.

Warnings

BIOS passwords are extremely difficult to remove if you forget it. It is recommended that you write down the password and keep it somewhere safe so that you won't get locked out of your computer.
