In some scenarios we need to reset the account password on the Mac for security purpose. How can you do that if your Mac password was leaked, or you plan to replace it with a new one?

Resetting password is quite simple if you are running macOS Sierra on your computer. And that’s exactly what we are gonna show you how to do in this step-by-step guide.

First of all, you can try the Recovery Mode method to reset your password. There is a tool provided in macOS as well as Mac OS X that help users change their passwords. And it does not even require your original password to make the change.

  1. (Re)boot your Mac, and once the screen goes black, hold down Command + R keys to boot your Mac into Recovery Mode. If you are running Mac OS X, hold the Option key when your Mac reboots, and then choose Recovery Mode that appears.
  2. As the macOS Utilities screen appears, click on the Utilities menu on the top bar, and then choose Terminal from the pull-down menu to open up this tool.
  3. As the Terminal loads, type the following command inside: resetpassword.
  4. Hit the Return key to bring up the Reset Password tool on your Mac.
  5. Select your account you wish to reset the password for from drop-down menu.
  6. Continue to enter a new password twice in the Reset Password screen, and enter a password hint (it is recommended to do so). Then click on Next to proceed.
  7. Click on Restart in the next window to reboot your Mac.

After your Mac finishes booting up, you can enter the new password to log in to it. Then you may be prompted that the system was unable to unlock your login keychain. All you need to do is to click the Create New Keychain button to proceed.

Besides, you can encrypt your startup disk using FileVault so that unauthorized users can’t read the data stored on your Mac without entering the right password.

Recovery Mode offers us a convenient way to reset our password. Meanwhile, it also poses potential threat to the security of the Mac. As it does not require the original password, it seems like anyone can change the account password using this method. How can you prevent others from changing your account password? The answer is to set up a firmware password so anyone who want to enter into the Recovery Mode for password change will be required to enter the separate firmware password.

  • Step 1: Enter into Recovery Mode, and choose Utilities > Firmware Password Utility.
  • Step 2: Click on Turn on Firmware Password button that appears in a new window.
  • Step 3: In the new window that pops up, enter a new password, verify it and click on Set Password button (if you have set up a firmware password before, you will be required to enter the old password). Then click on Quit Firmware Password Utility.

After the setup of firmware password, it will require entering the password when anyone want to wipe the system or replace with a new disk in Recovery Mode. Note that if you lose your firmware password, you can do nothing except for going to an Apple Retail Store or Apple Authorized Service Provider for help.
