Your Mac contains email messages, personal documents, images, and even a log of your Internet activities. It may have your banking details saved, among other sensitive information. Therefore, encrypting your Mac using a strong password will ensure the safety of your private data and give you complete control over who accesses your system in your absence.
Before diving into how you can password-protect your Mac, it is important to point out that you must maximize the security of your Apple ID. The Apple ID is the account that Mac users use to access several Apple services, including Apple Music, the App Store, FaceTime, iCloud, etc. The account includes the email address and password that you use to log in, along with the payment, contact, and security details you use regularly. In addition, the security of your account can be enhanced in the following ways:
- Use a strong password for your Apple ID, and the password must have 8 or more characters and include lower and uppercase letters and one number. You can even add punctuation marks or special characters to strengthen your password. When creating a strong password, you don’t have to worry about not remembering the password.

- Ensure the answer to your security question is difficult to guess.
- Use two-factor authentication to protect your account.
After you’ve strengthened your Apple ID and password, move on to password-protecting your Mac in the following ways.
1. Activate a screensaver password
One of the best ways to lock your Mac is to need a password when your system wakes up from Sleep mode or when the screensaver is disturbed. Once you’ve activated the screensaver password, you can put your device to sleep or switch on the screensaver when you leave your system.
The screensaver password is enabled by going to System Preferences > clicking Security & Privacy > selecting General and checking the “immediately” option next to the required password box. Then, you can invoke Sleep from the Apple menu, briefly pressing the Power button or closing the lid of your device.
You can even set up a hot corner for the screen saver by going to System Preferences > clicking Desktop & Screen Saver and then moving the cursor to the corner to begin the screensaver.
2. Encrypt the startup drive
FileVault is the in-built full-data encryption feature that you can use to protect the content of your startup drive. Use a strong password because it secures your account and unlocks your drive.
Enable FileVault by going to the Apple menu > choosing System Preferences > going to the Security & Privacy pane > selecting the FileVault tab > clicking the padlock to make changes > turning off FileVault.
You’ll be asked to select a method to unlock the disk if you lose your account password. For example, if you select iCloud, the recovery key for your disk will be stored by Apple on its servers, and you have to provide answers to three security questions to unlock the disk in the future.
Alternatively, you can select the recovery key method, and an additional window will pop up with the key.
3. Set a firmware password
Set a firmware password to prevent unauthorized users from starting your system from the recovery partition or another drive. Once the password is set, you’ll see the regular login window where you need to enter your user account password. If you try to start your Mac from macOS Recovery or another drive, your system will pause startup and display a lock icon.
However, firmware passwords can be enabled only on an Intel Mac, and the new Macs don’t support this. Instead, you can set a firmware password in the following steps.
- Restart your Mac, and as soon the screen turns black, hold down Command + R. Your system will boot from the recovery partition, and it might take longer than usual. Until you see a progress bar, keep holding down the keys.
- You’ll see the Utilities window when your Mac starts up. You need to select Utilities and select Firmware Password Utility. Then, select Turn On Firmware Password and enter a password. After that, select Set Password.
- Quit the Utility and restart your Mac. If someone attempts to start your device from another drive, you’ll be prompted for the firmware password.
These are some ways to password-protect your Mac and keep it safe from unauthorized access. First, ensure to use a strong password that nobody can guess. If you can forget the password, there are always ways to recover forgotten passwords or reset them.
