Password to enter the computer BIOS. How to set a password to log into a computer
Do you want to lock your computer before the operating system starts loading? Set a password for the BIOS. The following explains how to do this.
Different BIOS look different. Therefore, do not be surprised if the examples you see in the pictures are not the same as yours.
Let's look at 2 versions of BIOS. In the first, you can protect only the BIOS itself, and in the second, the PC boot.
Reboot and immediately after turning on the computer, press the F2, Delete or Esc key (it’s different everywhere). If you don’t know which buttons are needed, press them one by one.
After entering the settings, select BIOS Setting Password.
Then enter the password, press Enter, confirm it again and save the changes F10.
Installation completed.
Let's consider another version.
Go to the Security tab. In the Set Supervisor Password column, enter the password and confirm it.
Save the settings and finally press F10 – save and exit. Ready.
Now let's look at blocking the loading of the operating system. To do this, go to the Security tab again, enter the security code in the Set User Password column.
In the next line, select Enabled.
Confirm the changes.
A special feature of this version is that it will not be possible to set a password to boot the computer if it is not set to enter the BIOS. Otherwise, the Set User Password column will be inactive.
Go to settings and remove it (leave it blank) and save the changes.
All basic settings are stored in CMOS memory, which requires constant power supply from a battery installed on the motherboard. Therefore, to reset the settings to factory settings, you need to remove the battery, then insert it back.
CMOS memory can also be cleared by closing special jumpers. For information about them, see the instructions for your motherboard.
Today we will look at:
Keeping your PC, laptop or any other device safe from outside interference is one of the most important tasks if you want to protect your personal information. Among the ways to do this is setting a password, which, in the future, will need to be entered before starting the OS.
In this topic, we will tell you in detail how to set a password for entering the BIOS on a laptop, how to set passwords in the UEFI BIOS, and also how to enable similar protection on all-in-one PCs. We’ll also talk about what types of passwords there are in BIOS and how they differ.
BIOS AMI
One of the most famous and established types of BIOS - BIOS American Megatrends, has the following principle for setting passwords:
By doing this and rebooting your computer or laptop, you will instruct the system to require this password to enter the BIOS and the system itself.
BIOS Phoenix
Another BIOS that falls into the “standard” category is PhoenixBIOS. Here the principle of setting a password is slightly different.
BIOS UEFI
Passwords for UEFI BIOS are set in a similar way as in AMI:
As you can see, there is a lot in common with the previous BIOS versions already described.
Passwords in all-in-one PCs
If you use a monoblock, then setting a BIOS password will also not be difficult. Just like other similar devices, all-in-one PCs have a BIOS to control the entire system. You just have to find out how the BIOS version is used on the all-in-one PC in order to use one of the instructions described above to set a password.
Bottom line
Installing protective combinations is a necessary, but very responsible matter. When doing this, try not to forget your password, as otherwise it will be more difficult for you to regain access and control of the system. Speaking of lost passwords, in the following topics we will talk about how to safely reset your BIOS password without the help of specialists. In the meantime, you can leave your comments with questions on this topic below, and we will try to answer them in order to help you resolve certain incomprehensible issues.
With the help of a user account password in Windows, we can protect our data from third parties, but the truth is that it is not difficult to hack. Moreover, its actions are limited to the system and not the entire computer, so the data can be accessed using other operating systems, such as Linux, which can be run from a bootable flash drive or disk. To prevent this, you can set a password in the BIOS or UEFI.
A BIOS or UEFI password will protect your computer at the most fundamental level. Without entering it, you will not start the Windows operating system; you will not be able to boot from a disk or flash drive. Each time you turn on the computer, you will need to enter it to continue booting the system. We offer detailed instructions on how to set a password on your computer.
Things to keep in mind before setting a password.
Before jumping directly into the installation process, there are a few things to note. First, you need to set a password that you won’t forget. BIOS is not a social networking site where you can ask for reminders via email. Without knowing the password, you will not boot the computer.
Another thing is with the level of security. Although the BIOS password protects against unauthorized access, in the case of desktop computers it is easy to bypass it. It is enough to unwind the system unit and reset the BIOS (using a jumper or removing the battery from the motherboard for a while). In the case of laptops, access to these elements is more difficult, and this has its plus (from the security side) and minus (if you forget it).
Setting a password in BIOS
To install it in the BIOS you should not have any difficulties. When you start your PC, pay attention to the first screen - there will be information about which keys to press to Setup. Typically these are the Delete, F11/F12 or Escape keys.
After logging in, look for the “Security” tab. It contains all the security settings, including the Password function. Depending on the BIOS version or laptop model, you can simply select the Password or System Password and Admin Password option (the password blocks access to other settings).
In our case, use the System Password option, which prompts you for it immediately when you turn on the computer. Select this option, and then enter your password twice. Exit the BIOS saving the settings.
Now every time you start the computer, the BIOS will prompt you to enter a password to boot it further.
Setting a password in UEFI
UEFI is the successor to BIOS and if you have Windows 8, accessing UEFI is slightly different. The entire process of getting to UEFI settings can be found in the instructions on how to access the BIOS in Windows 8.
As soon as you go into the settings, just like in the BIOS, you need to find the Security option, enter the password twice and exit the BIOS, saving the settings.
We hope that the instructions provided on how to set a password on your computer will help you protect information from unauthorized access.
In order to set a password to boot your computer, or more correctly, to the BIOS, you must:
1. Restart the computer, and as soon as the computer starts loading on the screen (namely the computer, not the system itself), press continuously (press and release - only this is done quickly) F2 and DELETE (usually using one of these keys to open the bios), until your BIOS opens. Also pay attention to what is written on the screen when loading; the key with which it opens may be written there.
Because Because computers are different, the BIOS opens differently on them. On some, by pressing the DELETE key, on others, by pressing F2. And the pressing time is also different, on some you need to press the button immediately, on others after a post-signal. That is why I advise you to first look to see if the text mentions any keys at startup, so as not to fool yourself. Or simply, as I already said, press the above-mentioned keys one by one from the very start.
2. Entered. The interface, of course, will be different on different computers, but its essence is the same. Now you need to use the arrow keys to select Security.
3.Next, select Set Supervisor Password and press Enter. Enter the password and press Enter again. Now you have set a password for changing settings, i.e. next time if you want to change something in the BIOS, when you start it, it will ask for this same password. Without knowing this password, you cannot change anything in the BIOS settings.
Please note that inscriptions have appeared opposite the first two lines, which inform us about which passwords are set and which are not. Set - installed, Clear - not installed.
4.2. If you notice the User Password is marked Clear. What is this password? I answer. Supervisor Password, I repeat, is the password to access the BIOS settings. And if you set only this password, then this password will be used both as the password for starting the computer, and naturally as the password for its settings. This is convenient if one person uses the computer. If the computer is used by more than one person, then setting the User Password depends on whether you want to allow access to changes in BIOS settings. If you set this password, then when you start the computer, it will ask for exactly this password and nothing else. And the 1st password, I think you remembered what it was for - access to the BIOS settings. Those. in other words, you can set a Supervisor Password and not tell it to anyone, or set a User Password and tell it to those to whom you allow access. And those people who do not know the User Password will not be able to access the computer. And they won’t be able to reset the password either, because... they don't know the Supervisor Password. In general, it's up to you!
By the way, you can set both passwords to be the same, and this will be the same as setting only one Supervisor Password.
5.The last thing left to do is to save our settings and restart the computer. Again, use the arrow keys to select the Exit tab and highlight Exit Saving Changes, press Enter, confirm your selection by pressing the key again with Yes selected.
After saving, the computer will restart and ask for a password to continue working. If you entered the user password, then you need to enter it, if you entered only the supervisor password, then naturally you need to enter it.
If there is a need to remove passwords, then go to the BIOS and erase the passwords (just press Enter 2 times on the necessary items) in the items mentioned above and set Disabled to Password on Boot.
All! Be aware that the ability to set a boot password does not exist on all BIOSes, BUT it is possible on all BIOSes to enter the BIOS.
“, in which he promised to write about how to set a password in BIOS. So I’m keeping my promise, now I’ll write and show you how to install, remove, or reset the password in the BIOS.
But first, let's figure out how effective a password is in the BIOS system and how it helps protect your computer. Personally, I think that the password set in the BIOS does a better job of protecting your computer. It’s just that the password set in the operating system can be hacked programmatically, but the password in the BIOS, as far as I know, cannot.
After pressing “Enter”, a window will appear in which you need to enter a password. I can enter a password of 6 characters. We come up with and remember a good password, enter it and press “Enter”.
Another similar window will appear in which you need to enter a password confirmation. Enter the password again and press “Enter”.
That's it, the password is set, but after this setup, the password appeared only when I tried to enter the BIOS, and the computer turned on as usual without a password. In order for the password to appear when you start the computer, you need to make one more setting.
Therefore, we immediately select the tab and confirm the choice by pressing “Enter”.
Next we look for the item “Password Check”. Opposite it, I had the “Setup” parameter set, which meant asking for a password only when entering the BIOS. You need to change it to the value “Always”. We do this, press “Enter” and select “Always”. Now the password will be requested both when entering the BIOS and when starting the computer.
Now the most important thing is, don't forget to save your changes. Press the F10 key and “Enter”. The computer will reboot, and as soon as it starts up, a window will appear asking for a password. Enter our password and press “Enter” (sorry for the photo quality).
That's all, the BIOS password has been set, and your computer is now protected. Go ahead.
How to remove password in BIOS?
We have set a password, now we will shoot :). This is not yet hacking (resetting) a password, it is deleting it. Perhaps you didn’t like it, or you no longer need it.
We do everything the same way, go to the BIOS, select “BIOS Setting Password”. A window will appear asking you to enter a new password, do not enter anything, but immediately press “Enter”.
A window will appear with the inscription “Password uninstalled” (password removed), press “Enter” again. Save the result by pressing F10 and “Enter” again. That's it, the password has been deleted.
How to reset BIOS password?
First we set the password, then we deleted it, and now I’ll tell you how you can reset the password in the BIOS, that is, hack it. But this is not advice on hacking other people's computers, this is so that you can reset the password if you suddenly forget it.
As I already wrote at the beginning of the article, resetting a password on a regular computer is easier than on a laptop. Just in order to reset the password that is set in the BIOS system, we need to reset the BIOS itself. Read more about how to do this in the article. There you need to either close special contacts or remove the battery for a while. After which, the BIOS parameters will be reset, and the password will disappear with them. It's the same in laptops, it's just more difficult to disassemble.
Well, it seems like I wrote everything, try it, just be careful and don’t press anything unnecessary, otherwise you’ll get into trouble. Good luck!
