Although there are many variations in relation to BIOS and UEFI and you can even update the BIOS or UEFI of the motherboard, in general terms the process should be relatively similar. Given this, let’s see what are the common methods for both BIOS and UEFI. Still, before you begin, it is important to put in a password that you can remember.


The first thing to do is access the UEFI configuration options. This is usually done by pressing the F2 or Del key, although it varies depending on the motherboard model. Press the appropriate key until the UEFI configuration menu appears.

In most versions of UEFI you will find the “Security” section, where you will find the password settings. Use the mouse or keyboard to move towards this area and press on it.

Usually the “Supervisor password” and “User password”, we certainly recommend you to use the user option. All you have to do is double click or Enter on “User Password”. When doing the above, you must type the password and press Enter, you will be asked to enter the password again, do it and press enter.

After making the changes, go to the “Exit” tab, which is usually at the bottom right. Click on the option “Save changes and exit”. After this the changes should be saved and when UEFI boots again, the password will be asked.


While there are differences in the process with the BIOS is similar to that of UEFI. The first thing to do is enter by pressing the appropriate keys to enter the BIOS (Del, F2, etc). Once inside, locate the “Security” section.

Within security, select the option “password” as with UEFI, there is the option of supervisor and user. In any case, in most BIOS, another option appears “Define password”(Set password) press enter on it. After this, enter the password, if it is required again, type it again and press enter.

To finish the process go to “Exit” (Exit). Here select the option “save changes and exit”. Once you completely exit the BIOS, you should already have the password set.

On the other hand, if you want to remove the BIOS password, know that the process is quite simple. Even so, as we pointed out before, it is very important that you remember the key.
