The BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is the first software to run when you power on your computer. It is responsible for initializing and testing the hardware components, and it allows you to configure the boot order, time, and other settings. One of the security features of the BIOS/UEFI is the ability to set a password, which prevents unauthorized access to these settings. However, there may come a time when you need to change your BIOS password, whether it’s because you’ve forgotten the current one, you want to update it for security reasons, or you’re transferring ownership of the computer. In this article, we will guide you through the process of changing your BIOS password in UEFI.
Understanding UEFI and BIOS Passwords
Before we dive into the process of changing the BIOS password, it’s essential to understand the difference between UEFI and BIOS, as well as the types of passwords you can set. UEFI is a more modern replacement for the traditional BIOS, offering faster boot times, better security, and support for larger storage devices. Both UEFI and BIOS allow you to set passwords to protect your system’s settings and data.
There are typically two types of passwords you can set in the BIOS/UEFI: the Administrator password (also known as the Supervisor password) and the User password (also known as the User Setup password). The Administrator password gives you full access to all settings in the BIOS/UEFI, including the ability to change the boot order, set up boot passwords, and configure other security settings. The User password, on the other hand, only allows access to the system but does not permit changes to the BIOS/UEFI settings.
