A BIOS password (or UEFI setup password) is a firmware-level gate that can block changes to boot settings and, on some systems, block access to the BIOS setup screen itself. If you’re changing ownership, securing a lab PC, or cleaning up your own configuration, knowing how to create and remove it matters.
This guide covers the quickest legitimate ways to create and delete a BIOS password. If you forgot the password, you’ll also find the fastest official recovery routes for common manufacturers—without relying on risky “bypass” folklore that can brick hardware or void warranties.

What a BIOS Password Actually Controls (and Why It Matters)
BIOS password behavior varies by vendor, but most systems use one or both of these controls:
- Setup/Administrator password: Protects BIOS/UEFI settings (boot order, secure boot, virtualization settings, SATA/NVMe modes, and sometimes overclocking).
- Power-on/Boot password: Can also prompt during startup to prevent booting until you enter the password.
If you’re troubleshooting “can’t change boot order” or “can’t enter BIOS,” you’re usually dealing with the Setup/Admin password. If you’re seeing a prompt before the OS loads, it’s commonly the Boot/Power-on password.

Before You Start: Prerequisites and Safety Checks
Firmware settings are sensitive, and some paths differ between legacy BIOS and UEFI. Do these checks first so you don’t waste time.
- Confirm ownership: Only attempt password removal on systems you own or manage with authorization.
- Use stable power: Plug a desktop into wall power. For laptops, use the AC adapter and keep the battery installed if possible.
- Know your firmware key: Be ready to press the setup hotkey at boot. Common keys include F2, F10, F12, Del, or Esc.
- Record current settings: If you can enter BIOS setup, note critical items like boot mode (UEFI vs Legacy), Secure Boot state, and drive mode (AHCI/RAID/NVMe).
- Plan for bit-lockers: A BIOS/UEFI password change typically won’t break Windows, but a major reset of firmware might interact with BitLocker prompts or TPM state depending on your configuration.
How to Create a BIOS Password (Fastest Common Method)
Creating a BIOS password is usually quick: enter setup, find Security → Password, set the new password, save, and reboot. The exact menu names vary by vendor.
1) Enter BIOS/UEFI Setup
Restart the computer and immediately tap the setup key (for example F2 on many Dell/Lenovo systems, F10 on many HP systems). If you miss the window, reboot and try again.
2) Find the Security Password Screen
Look for one of these menu paths:
- Security → Set Supervisor Password / Administrator Password
- Security → Password / Password Configuration
- Security → UEFI Setup Password (common on newer systems)
If you see both “Setup” and “Power-on,” decide which lock you want.
3) Choose the Password Type and Enter Your New Password
Typical firmware prompts:
- Enter new password
- Confirm new password
Use a password you can reliably remember or store securely. Many setups enforce limits like 4–20 characters or only allow alphanumeric values. If a screen says characters are restricted, don’t guess—follow the on-screen rules.
4) Save and Exit
Select Save & Exit (often F10 or an on-screen option). The system will reboot and begin enforcing the password at the next relevant prompt.
How to Delete/Remove a BIOS Password (When You Know the Current Password)
If you already know the current password, removal is usually the fastest and safest route. Most systems require the current password to clear the stored hash.

1) Boot into BIOS/UEFI Setup
Enter BIOS setup using your current password prompt (if applicable). If the system asks for a password before it will even show the setup UI, you must enter the correct one first.
2) Navigate Back to the Password Setting
Find the same Security menu entry you used to set the password. Common names include:
- Supervisor Password / Administrator Password
- UEFI Setup Password
- Set Power-On Password
3) Select Clear/Disable
Look for one of these actions:
- Change (sometimes lets you overwrite but not always clear)
- Clear
- Disable
- Enter Password to Disable
On many firmwares, the clear option won’t appear until the password is set and you’re logged in with the correct current password.
4) Save Changes
After you clear/disable, save and exit. Reboot to confirm the password prompt is gone and that BIOS settings can be edited freely.
Fastest Legit Ways to Recover if You Forgot the BIOS Password
If you forgot the password, avoid random “short the pins” instructions from forums. The quickest reliable methods are the vendor-supported ones that match your model. Your goal is to clear the firmware password through an authorized recovery flow.
Option A: Use the Vendor’s Password Recovery Process
Many OEMs provide a controlled recovery flow for BIOS setup passwords. You typically need the exact device model and service tag/serial number. The process often involves generating a recovery key or request code and verifying ownership.
How it usually plays out:
- Identify the exact brand and model (e.g., Dell Latitude 7xxx, HP ProBook, Lenovo ThinkPad).
- Find the specific support page for BIOS/UEFI password recovery (not a generic “forgot password” page).
- Follow the prompts to retrieve the required identifiers (often serial/service tag).
- Use the vendor’s recovery steps to obtain an authorized key or procedure.
Option B: Contact OEM Support with Proof of Ownership
This is often the fastest path in real life. Provide the service tag/serial number, purchase proof, and the exact symptoms (setup password prompt vs power-on prompt). OEM support can advise the official next steps for your firmware generation.

Common Problems and What to Try Next
Even with the right instructions, firmware password workflows can fail due to timing, keyboard layouts, or firmware state. Here are the most common issues.
You Can’t Enter BIOS Setup at All
If you see a prompt before BIOS loads (instead of after), you may be dealing with a Power-on/Boot password. The fix is still the same concept: you need the current password or a vendor-authorized recovery method.
- Try a different keyboard port (USB 2.0 ports often initialize earlier than USB 3.0 on older systems).
- Power cycle fully: shut down, wait 10–15 seconds, then boot again.
The Password Is Rejected Even Though You Know It
Common causes:
- Keyboard layout mismatch: Some firmware assumes a US layout. If your password includes symbols, verify what the firmware expects.
- Caps Lock/Num Lock: Some setups treat uppercase/lowercase as different characters.
- Wrong password type: Setup vs power-on can require different passwords.
You Cleared the Password but Still Get Prompt
This can happen if only one password type was cleared. For example, the Setup password may be removed, but the Boot/Power-on password remains enabled.
- Enter BIOS setup using the newly cleared setup access.
- Check both the Setup/Admin and Power-on/Boot password options.
- Save and reboot after clearing each relevant setting.
BIOS Save Doesn’t Persist
If changes revert after reboot, check for:
- Missing Save & Exit step.
- Power instability during save.
- Firmware update requirement (rare, but some older platforms behave oddly).
Firmware Update Isn’t a Password Reset
Updating BIOS firmware usually doesn’t clear a password. In many cases it can keep the same password state to prevent security bypass. Treat firmware updates as a separate maintenance task, not your password recovery tool.

People often mix BIOS passwords with OS encryption or boot security controls. Here’s how the common pieces differ.
Free tools Windows power users keep installed
One-click scans. No signup required.
| Control | Where it triggers | What it protects |
|---|---|---|
| BIOS/UEFI Setup Password | Before BIOS setup can be changed | Firmware settings (boot order, Secure Boot config, device modes) |
| BIOS/UEFI Power-on/Boot Password | During boot before OS | Prevents boot until password entry (varies by model) |
| BitLocker | During Windows startup | Protects data volume encryption keys |
| Secure Boot | During the boot chain | Verifies signatures of bootloaders/firmware components |
If you can boot into Windows but can’t edit firmware, it’s likely the BIOS/UEFI password only. If Windows prompts for recovery keys, that’s more likely BitLocker/TPM-related, not the BIOS password itself.

Security and Data Considerations
BIOS passwords are security boundaries, but they can also create operational friction. If you manage multiple devices, treat BIOS passwords like credentials: store them securely and document how authorized admins recover them.
- Use a password manager for setup passwords you intend to clear later.
- For fleets, maintain an IT playbook for authorized recovery using model and serial-based processes.
- Avoid unofficial bypass methods: Unverified reset techniques can damage firmware settings or disrupt TPM/Secure Boot workflows.
FAQs
Can I remove a BIOS password without the current password?
Sometimes, but the safe and authorized path is to use your OEM’s official recovery process or contact support with proof of ownership. Firmware designers typically block simple clearing to prevent unauthorized access.
Will clearing the BIOS password reset my computer clock, boot order, or storage settings?
It can. Some firmware clears can restore defaults for boot mode and related settings. After removal, check boot order (UEFI vs Legacy), Secure Boot state, and drive mode (AHCI/RAID) to ensure your OS still boots as expected.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Does reinstalling Windows remove a BIOS password?
No. Windows reinstallation affects the OS, not firmware security. You still need access to the BIOS/UEFI setup password (or authorized recovery) to change firmware settings.
What’s the difference between a Setup password and a Power-on password?
A Setup password controls access to BIOS/UEFI configuration. A Power-on/Boot password can require a password during startup before the system can proceed to the OS or BIOS.
Is a BIOS password the same as an administrator password in Windows?
Not at all. A BIOS password is enforced by firmware before the OS runs, while Windows administrator passwords control user access after the OS boots.
Bottom Line
Creating or deleting a BIOS password is usually straightforward when you know the current password: enter BIOS setup, find the Security password setting, clear/disable it, and save. The fastest path when you forgot it is using your OEM’s official recovery process tied to your device model and serial/service tag.
