Lock down your Mac user account
Lock down your Mac and get up to speed with super-strong security. Alex Blake shows how.
Securing your Mac’s user account doesn’t have to be an arduous process. There are a few quick and easy tweaks you can do that will make a big difference.
If you get locked out of your account, you can reset your password in macOS Recovery. But if you can do that, someone else can too. It’s therefore a good idea to restrict access to Recovery by using a firmware password.
To enable that, restart your Mac and hold command-R until you enter macOS Recovery. Click Utilities in the menu bar, then choose Boot Security Utility (sometimes called Firmware Password Utility). Click Turn On Firmware Password, enter a strong password, click Set Password, then restart your Mac.
There are plenty of other options at your disposal. For example, it’s a good idea to create a new admin user and remove the administrator privileges from your regular account. That way, powerful controls are locked behind a separate account. Read on for more super-secure suggestions.
