The above method to reset login password running macOS Sierra is quite easy. But you must have noticed one thing: anybody who has got physical access to your Mac can change or reset your password. This challenges the security of your Mac; you need to take extra care about this security loophole. In this situation, you can use FileVault or Firmware Passwords utilities offered by Mac.


It is a default encryption utility that comes with all Macs from Apple. Users can encrypt all the data by using this robust tool, which can protect it with a password and a recovery key. Whenever you access your account, you must unlock the encrypted hard drive by entering FileVault password.

You may be puzzled as how this can protect your data. The answer is that even as someone resets your Mac’s password, they cannot open your hard disk.

Firmware Passwords

If you are not happy with FileVault option, you can lock your Mac with a higher level of security wall – Firmware Passwords. This will create a lock on your Mac at the firmware level. For this, you are required to go into Recovery Mode and select ‘Firmware Password Utility’ from Utilities menu. If your Mac is accessed by an unknown user and the user wants to boot into Recovery Mode, or Single User Mode or tries to use Mac in Target Disk Mode to transfer data, s/he will have to enter your Firmware password. Note that you don’t need to enter Firmware password for log in.

Also remember that you cannot reset your Firmware password easily, and therefore, you should use this utility only when it is essential for you. A word of caution: you need to contact Apple in case you forgot Firmware password.
