Here’s why you need to encrypt your FileVault disk

Gone are the days when you could set your user password to 12345 or completely skip the lock screen. Our devices now store a lot of information that we value, which means that setting up some measures to protect against unauthorized access is just common sense.

The built-in macOS FileVault tool is a great solution to protect your data — allowing it to encrypt your boot disk, protecting your files. If you want to know what FileVault disk encryption is, continue with this blog post as we will discuss the advantages and disadvantages of using it and guide you through the process of enabling (or disabling) FileVault encryption (if necessary).

Hopefully by the end of this article you will have the final answer to the question: “Should I use FileVault disk encryption on my device?” Let’s get started.

What is FileVault?

FileVault full disk encryption is a tool in your macOS that helps you protect the data on your boot disk. FileVault full disk encryption or FileVault 2 provides XTS-AES-128 full disk encryption with a 256-bit key.

It is easily installed on your device and protects your files from unwanted access. With FileVault turned on, you’ll need to log in to your device account each time before use – either with a password or Touch ID.

FileVault 2 is available for Macs running OS X Lion or later.

How does FileVault work?

Simply put, FileVault is Mac encryption. Helps prevent unauthorized access to the data you store on your device.

Once turned on, FileVault encrypts the files you store and create on your device. Existing files on your boot disk will be encrypted when you turn on this tool, and any new ones you create will be automatically encrypted as they are saved to disk – encryption on your Macintosh will take place in the background when your device is awake and on.

Should I use FileVault disk encryption?

FileVault is an amazing encryption solution that could benefit any Mac user. The tool helps increase the protection of your files from brute force attacks.

The only possible drawback is that you can’t remove the automatic device lock with FileVault turned on (meaning you’ll have to log in to your Mac account every time you load or fall asleep) and that the process could take a small CPU to run encryption in background (which could increase if you store very large files).

So, if you don’t have anything of value on your Mac or it’s always locked in a secure location where no one but you can access it, you can opt out of enabling FileVault. Otherwise, FileVault is a great way to better protect your files.
