How to password protect your Mac
With so many security threats about, having a Mac password is the first step towards keeping your Mac safe. And crucially, it needs to be a smart one. In this article, we look at how to set a password on Mac that another person or a smart virus would find difficult to crack.
Even according to recent studies, too many people are still using passwords such as 1234 or Password or Password1 - ones that are too simple to be secure. This means that your Mac is easier to break into and your data is vulnerable.
On new Mac’s, you can use biometrics: known as TouchID. Already popular on iPhone’s and iPad’s, this is another layer of security that is unique to you, making them almost impossible to hack into. However, for everyone who still uses passwords, here is how to set a password for a Mac.
#1: Set a FirmWare password
Although you might not realize it, your Mac is vulnerable, even with a strong password.
Did you know that your Mac could be vulnerable to someone booting it up using an external hard drive? This method sidesteps every security measure in place.
One way to remove the worry of someone booting your Mac using an external hard-drive is to set up a Firmware password.
Before you do this, please note that it can’t be easily reset. If you forget it, you are probably going to need an Apple Genius Bar or certified reseller/expert to fix the problem. Firmware passwords live in a special area of persistent memory on your Mac's mainboard, so take good care of this one. Here is how you set it up:
- Power your Mac down;
- Now switch it back on while holding down the Command (⌘) and R keys to switch on Recovery Mode;
- Wait until the macOS Utilities screen appears, and then click on Utilities > Startup Security Utility;
- Now you can switch on Firmware password;
- Enter a new password (something secure and different from other passwords already in use) and confirm it;
- Now click Set Password then Quit Firmware Password Utility
- And finally, click on the Apple () menu, then > Restart
#2: Delete and passwords (create new ones)
Another way to improve security is to start from scratch. Always a good move if you are concerned passwords might have been compromised. To do this, follow these steps:
- Download CleanMyMac X (for free, here)
- Click on the Privacy module;
- Use this to erase old passwords
- Now follow Step #3 (below) and #1 (above) - if you want extra security - to create stronger new passwords on every app and account you want to reset.
#3: Make your new password more secure
What we all need is layers of security.
Use a variable mix of numbers and letters (which is one of the main reasons people use password software to retain and remember all of them).
When you use a mix of lower case letters, UPPER CASE LETTERS, numbers (ideally not in sequence, e.g. 4179; and not something that someone could easily guess, such as a birthday) and symbols (e.g. $%@) you make a password so much more secure than if you only used one or two of those characters.
#4: Different device: Different passwords
It might sound like common sense, from a security perspective, but what security experts find is that convenience often beats other concerns.
To properly protect your Mac and all it contains, you need to set a password that isn't used on another device. Such as an iPhone or iPad. Make sure your iCloud password is not the same as your Mac’s, because if someone gets one device and that is connected through iCloud to your Mac then everything on the Mac is at risk.
So use different passwords for different devices, especially when there is a cloud connection that potentially puts everything in the reach of criminals.
#5: Scan for password-stealing software (keyloggers)
Something else to watch out for is keylogger software. Also known as keystroke software. This records everything you type. So when typing in a password, or even when a password is entered using a keychain, this malicious software records it and unless it’s been detected and shut down, sends the data back to whoever wants to use it.
Here is how you remove this particularly unwanted and high-risk threat:
- Download CleanMyMac X (for free, here)
- Click on the Malware removal module;
- This will show you any infection, viruses and keylogger scanners hiding within your Mac;
- Now use it to safely and quickly delete them;
- It’s always worth resetting your Mac after this to clear everything out of cookies and cache.
Passwords keep us safe
Passwords keep the wolf from the door. In the digital world, bots and cybercriminals are waiting to exploit any vulnerability and weakness, starting with our passwords. We need every defense we can possibly set up to protect us.
Having a secure password is the first step towards keeping your Mac protected. Beyond that, it helps to know that you’ve got apps that can monitor the health of your Mac and protect it from malware, viruses, and keylogger tracking software. CleanMyMac X can do both: Improve the performance of a Mac and remove malicious software, malware and other viruses.
