Password Protect

Are you afraid that in your absence someone might access your PC? So just lock it up with a password through the BIOS. This way, it will ask for a password every time it’s turned on before the OS loads up.

The level of security you can set in a PC depends upon the BIOS version and type. Normally, there are three options you can configure. These are a Supervisor password, User password, and Password on boot. Check that your BIOS has these. Some don’t have the third option because of which they will not ask for a password during boot up. This will only protect your BIOS settings, and will not be able to prevent others from using your PC. Normally, you’ll find a separate security section where you can configure all options.

When specifying a password, you’ll have to enter it twice, where the second one reconfirms the first. A Supervisor password is normally meant to give you full access to your system BIOS. A User password is to restrict BIOS access. The level of restrictions range from read only, limited, to no access. This is so that no one other than the one with the Supervisor password can make changes to the BIOS. If you get hassled with the password, you can remove it too. For this, go to the security section in the BIOS, and redefine the password. When it asks for a password, press enter and it will clear the password.

Some systems require you to first enter your older password before doing this.
