How to Make A Password Protected Zip File Mac

Sometimes we need to send important files over the internet and we want to make sure that these files are secure from being hacked. One way to ensure the security of the files we send is by encrypting them using a password-protected zip file. A password-protected zip file is one that is encrypted and cannot be accessed without a password. In this blog post, we will discuss some methods on how to make a password-protected zip file on a Mac.

What’s Needed

To make a password-protected zip file on a Mac, you will need:

1. A Mac computer with ZIP software installed.
2. The file(s) or folder(s) that you want to compress and encrypt in a password-protected zip file.
3. A strong password, which is a combination of numbers, letters, and symbols.

What Should I Pay Attention to?

Before making a password-protected zip file, consider the following:

1. Do not use a password that is easy to guess.
2. Create a password that is at least eight characters long and includes a combination of upper and lower-case letters, numbers, and symbols.
3. Make sure you remember your password or store it in a secure place as there is no way to recover it if you forget.
4. Avoid using personal information in your password, such as your name, date of birth, or address.

Method 1: Using the Terminal

1. Open Terminal. You can find it in the Utilities folder in Applications or by using the search function.
2. Navigate to the folder where your files are stored using the "cd" command.
3. Use the following command to compress your file(s) or folder(s) into a password-protected zip file: zip -er file(s) or folder(s)
4. Enter a password when prompted.
5. Press Enter to confirm the password.
6. Your password-protected zip file is now created in the same directory as your original file but with a .zip extension.


– The zip command is pre-installed on Macs.
– The Terminal method provides stronger encryption.


– Not everyone is comfortable using Terminal.
– This method can be time-consuming if you are not familiar with Terminal commands.

Method 2: Using Finder

1. Select the file(s) or folder(s) that you want to encrypt.
2. Right-click on the file(s) or folder(s) and select "Compress items".
3. A compressed file with a .zip extension will be created.
4. Right-click on the compressed file and select "Get Info".
5. Under "Name and Extension", type ".zip" at the end of the existing name.
6. Open the compressed file and select "File" from the menu bar.
7. Click on "Set password" and choose a password.
8. Your password-protected zip file is now created.


– It is a quick and easy method.
– This method does not require any command line knowledge.


– Finder method compression may result in a larger file size.
– This method provides weaker encryption.

Method 3: Using Third-party software

There are many third-party software options available, such as Keka, which can be downloaded from the App Store or other websites.

1. Download and install the third-party software of your choosing.
2. Open the application.
3. Drag and drop the files or folder you want to zip to the application window.
4. Set a password for the compressed file.
5. Click on "Compress" or "Create archive".
6. Your password-protected zip file is now created.


– Third-party software might provide stronger encryption.
– Some third-party software can create zip files with smaller file sizes.


– This method can be expensive.
– Third-party software may not be compatible with all Mac operating systems.
