Cybercrime is the No. 1 risk when storing or sharing files online, which means you should ensure your zip files are as secure as possible.
Adding a password to your zip file helps protect the contents, especially if they contain sensitive information. So, how do you make a password-protected zip file? We’ll explain everything you need to know about creating one.
6 Ways to Make Password-Protected Zip File
1. Mac Terminal
For Mac users, creating a password for your zip file can be done using the Terminal application on whichever IOS you use.
Pros: The Terminal application is free for Mac users, and your zip files are fully compatible when sent to Windows and Linux users.

Create a new zip file by typing in the command "zip -er desiredfilename.zip."
Drag the files you want to be added to the zip file and drop them in the Terminal window.

2. EFS, Windows 10 Pro
EFS is Windows 10 Pro's Encrypting File System.

For full password protection, we suggest using WinZip in addition to EFS.

This is the recommended platform for Windows users who don’t have Windows 10 Pro. To add a password to zip files in most Windows computers, you'll have to use a third-party app like WinZip.
Pros: WinZip is compatible with Windows and is simple to install on your Windows device. It’s easy to use with a quick three-step process, and it’s initially free.

Right-click on these files and open the 7-Zip menu.
Select "Add to Archive," which will open the encryption menu.

When to Use a Zip File
Zip files have been around for a long time and have always been a popular way to share large documents in one location. As technology has advanced, many people are moving away from using zip files because they perceive them as unsafe, but sometimes, using a zip file is a good idea.
Sending Large Amounts of Information
Have you ever tried to send documents or folders over email only to be told the file size is too large? This is because email platforms have limits on the size of your content, and if you're sending multiple large documents, this can be challenging.
Instead of sending large amounts of information in small batches, you can compress all that information into one folder known as the zip file.
Organizing and Sharing Large Files
Sharing large files can quickly turn into a disorganized system if you have a lot of them.
Compressing all the information into one file means you’re able to keep track of which information is where. It helps you stay organized, and it helps the receiver of the files, as they don't have to sift through tons of muddled information.
Needing a Faster Transfer
Zipped files are a much more organized way of transferring data but are also a faster option. You'll notice the transfer takes longer when sending large files, even with a fast internet connection. Compressing that information into one smaller file will result in a faster transfer.
