Macs have a special lock called a firmware password. It adds extra safety to your computer. A firmware password stops others from starting your Mac with a different disk or changing important settings.
This password is different from your regular login password. You set it up in a special part of your Mac called macOS Recovery. Once it’s on, you need to enter it before your Mac starts up normally.
Setting up a firmware password is easy. You can do it yourself in a few steps. But be careful – if you forget this password, you might need Apple’s help to use your Mac again.
Firmware Password on Mac: Complete Guide
A firmware password adds an extra layer of security to your Mac by preventing unauthorized access at the hardware level. This comprehensive guide will walk you through everything you need to know about setting up, managing, and removing firmware passwords on your Mac.
What is a Firmware Password?
A firmware password (also called an EFI password) is a security feature that:
- Prevents unauthorized booting from external drives or USB devices
- Blocks access to Recovery Mode, Single User Mode, and Target Disk Mode
- Protects against someone resetting your Mac’s NVRAM/PRAM
- Stops unauthorized reinstallation of macOS
- Adds security even if someone physically accesses your Mac
Important Note
A firmware password is different from:
- Your user account password (for logging into macOS)
- Your FileVault password (for disk encryption)
- Your iCloud password
When Should You Use a Firmware Password?
Good Reasons to Enable:
- You travel frequently with your Mac laptop
- Your Mac contains sensitive business or personal data
- You work in a shared office environment
- You want maximum physical security
- You’re in a high-security field (legal, medical, financial, etc.)
Consider Carefully:
- You may forget the password (recovery is difficult)
- It can complicate legitimate troubleshooting
- Hardware repairs may require removal
How to Set a Firmware Password
For Apple Silicon Macs (M1, M2, M3, M4 and later)
Note: Apple Silicon Macs handle firmware security differently. The process is more streamlined:
- Shut down your Mac completely
- Press and hold the power button until you see “Loading startup options”
- Click Options > Continue
- Select your user account and enter your password
- From the menu bar, choose Utilities > Startup Security Utility
- Click Turn On Firmware Password (or Security Policy)
- Create and verify your firmware password
- Click Set Password
- Restart your Mac
For Intel-Based Macs
- Shut down your Mac completely
- Turn it on and immediately press and hold Command (⌘) + R
- Continue holding until you see the Apple logo or spinning globe
- Wait for Recovery Mode to load
- From the menu bar, select Utilities > Firmware Password Utility (or Startup Security Utility on newer Intel Macs)
- Click Turn On Firmware Password
- Enter your desired password twice
- Click Set Password
- Make note of your password in a secure location
- Restart your Mac
Password Requirements
- Minimum length varies by Mac model (typically 4+ characters)
- Can include letters, numbers, and special characters
- Case-sensitive (remember exact capitalization)
- Should be memorable but secure
- Different from your login password (recommended)
What Happens When Firmware Password is Enabled?
When someone tries to:
- Boot from an external drive: They’ll need the firmware password
- Enter Recovery Mode: Password required
- Reset NVRAM/PRAM: Password required
- Use Target Disk Mode: Password required
- Change startup disk: Password required
- Boot in Safe Mode: Password required (on some models)
What Still Works Without the Password?

What If You Forgot Your Firmware Password?
This is a serious situation with limited options:
For Apple Silicon Macs
- Contact Apple Support immediately
- Prepare proof of purchase (original receipt, invoice, or order confirmation)
- Visit an Apple Store or Authorized Service Provider in person
- They can verify ownership and help remove the password
- Process typically requires photo ID and proof of purchase
For Intel-Based Macs
Option 1: Apple Support (Recommended)
- Contact Apple Support or visit an Apple Store
- Bring your Mac and original proof of purchase
- Bring government-issued photo ID
- Apple can remove the firmware password after verifying ownership
Option 2: Hardware Configuration Change
- For some older Intel Macs, changing RAM configuration may help
- This method is not reliable and doesn’t work on newer models
- Not recommended as a primary solution
Important Notes on Password Recovery
- No backdoor exists to bypass a firmware password
- Apple takes this very seriously for security reasons
- Proof of ownership is mandatory
- The process may take several days
- Third-party services claiming to remove firmware passwords are often scams
Firmware Password Best Practices
Do’s
✅ Write down your password and store it securely (password manager, safe) ✅ Use a memorable but unique password different from other passwords ✅ Document the date you set it ✅ Keep proof of purchase for your Mac accessible ✅ Test the password after setting it to ensure it works ✅ Inform your IT department if it’s a work computer ✅ Update your password periodically (every 6-12 months)
Don’ts
❌ Don’t use your login password (defeats the purpose) ❌ Don’t create a password you’ll forget (recovery is very difficult) ❌ Don’t lose your proof of purchase (needed for recovery) ❌ Don’t share the password unless absolutely necessary ❌ Don’t assume you can bypass it (you can’t) ❌ Don’t rely solely on memory (write it down securely)
Checking If Firmware Password is Enabled
Method 1: Startup Test
- Restart your Mac
- Hold Option (⌥) key immediately
- If you see a password lock icon, firmware password is enabled
Method 2: Terminal Command (macOS Mojave and earlier)
sudo firmwarepasswd -check
- Returns “Yes” if enabled, “No” if disabled
- May not work on newer macOS versions
Method 3: Recovery Mode
- Restart into Recovery Mode
- If you need a password to access Recovery, it’s enabled
Firmware Password vs. Other Security Features
| Feature | Firmware Password | FileVault | User Password |
|---|---|---|---|
| Protects Against | Unauthorized booting | Disk access | User account access |
| Level | Hardware | Encryption | Software |
| Required For | Startup changes | Reading disk data | Logging in |
| Can Be Reset | Very difficult | Difficult | Easier |
| Best Used With | FileVault + Strong user password | Firmware password | Both above |
Recommended Security Setup
For maximum protection, use all three:
- Firmware Password – Prevents hardware-level access
- FileVault – Encrypts your entire disk
- Strong User Password – Protects your account
Troubleshooting Common Issues
Problem: Can’t Access Firmware Password Utility

- Forgetting the password can lock you out of your Mac
Setting Up a Firmware Password on Mac
A firmware password adds an extra layer of security to your Mac. It stops others from booting your Mac from external devices or changing startup settings without your knowledge.
Accessing Firmware Password Utility
To set up a firmware password you need to use the Firmware Password Utility. First, restart your Mac and hold Command-R as it boots up. This puts your Mac in Recovery Mode. Once in Recovery Mode click on the Utilities menu at the top of the screen. Then select Startup Security Utility or Firmware Password Utility depending on your Mac model.
You’ll need to enter your admin password to access these tools. This is the same password you use to log in to your Mac. Make sure you have this password ready before you start.
Activating Firmware Password
In the Startup Security Utility click “Turn On Firmware Password.” A box will pop up asking you to create a new password. Choose a strong password that’s hard to guess but easy for you to remember. Type it in twice to confirm.
Be careful! If you forget this password you’ll need Apple’s help to reset it. Write it down and keep it in a safe place. Once you’ve set the password click “Set Password” to turn it on.
Your Mac will now ask for this password when you try to boot from an external drive or change startup settings.
Securing Mac with FileVault
For even more security turn on FileVault. FileVault encrypts your whole disk. This keeps your data safe if someone steals your Mac. To turn on FileVault go to System Preferences then click Security & Privacy.
Click the FileVault tab and then click “Turn On FileVault.” You’ll need to choose how to unlock your disk and reset your password if you forget it. You can use your iCloud account or create a recovery key.
FileVault works with your firmware password to keep your Mac and data extra safe.
